Pumpkin HU AL-C0241, can't download mapping for Sygic GPS & Navigation app - Android Head-Units

Hello Members
I've got the head unit above, it's an Android 4.4.4 , at 1gig of Ram.
I can install the Sygic app from the store without any problems, but when the setup comes to needing to download the mapping, it can't, it either reports there's a connection issue, or the round timer just keeps rotating.
I have downloaded other navigation software IE Copilot, and there's been no problem.
I can surf the web, use my Gmail, download apps.
I've tried setting up Sygic using my home router internet, and my tether connection from my phone with no luck.
Is there something I can do, or what's the issue with Sygic?
Help would be great thanks

This is because Sygic wants to identify your unit as a cellphone and wants a valid and unique cellphone IMEI number. The Android head units all have a fake and the same IMEI number because they don't actually have cellphone modems built in, so Sygic will not be able to properly register with the download server because its trying to this fake IMEI number.
There is a way around this issue:
In your Sygic Navigation folder after you run it one time (on my device it's under /sdcard/SygicNavigation), there is a folder called Android. Within that folder, create a file called settings_overload.ini and add the following lines:
[RuntimeSettings]
m_strDrvDevice=mac
I also had tochange the same m_strDrvDevice paramater in the settings.ini file from IMEI to mac to get it to work for me, so you might want to do that as well.
You will need to edit the files using "RootExplorer".
After you do that, then Sygic will be able to properly talk to the download servers and register your unit to download maps.
This should really be in the Wiki/FAQ.

What i did to solve this was to install and run it on my Galaxy tab, then just copied the sygic folder over to My HU and works like a charm now.
Probably could use phone as well.

Thanks nixfu and nujackk for the help, but can I just mention that my Android headunit isn't rooted, so can I still use RootExplorer, and do I install RootExplorer on the Headunit?

Hello Members
I just wanted to again say thanks for the information, I realised that the only way I can do the edits recommended by nixfu, is by 'Rooting' the Pumpkin Head unit, which I have no knowledge on how to do it, and which I rather not do anyway.
I did manage to find a similar navigationally app called Navigon UK, which installed without problem, had no issues in downloading and installing the maps, and has pretty much the same 'Assisted lane guidance' (like Sygic's 'Dynamic lane assist).
I see no point in Sygic being so restrictive in presenting this hardware compatibility issue, and as long as the user has paid for the applications licence, and is a registered user on there download servers, there shouldn't be this unnecessary obstacle.
kind regards
Livio

Google navigator

Hi,
Have anybody tried google navigator on the HD. I heard it's supposed to work with the hd. Anybody know if a dataconnection is needed, or can we download the maps and use it "offline" with the built in GPS reciever ??
anybody know where we can find a trial ?

Attached Google.
This is freeware
thx for reply. But isn't this the same that came pre-installed with the HD.
I tried Google Maps but that uses the data connection. I heard on google navigation you can save maps on storage and the use it "offline", so no need of data-connection, only GPS reciever.
Sorry, I should have read your thread properly, been a long day.
Google Navigator attached
I haven't used this application to be honest, but just installed it and a data connection appears to be required. I'll play with it and let you know if this can be disabled.
I have also downloaded the trial from http://www.pdafun.net/
and first time I started it I saw it downloded dato. I then used HD tweak to stop all data connection, and went in to Google navigator and changed som settings.
I can still start the prorgam wihtout any problems and activated GPS. It find my postition(still noe data connection used, yet). But don't know how to get a map. I only see a "world" map.
SO would be nice to know how we can download offlien maps so we can use with GPS and not need to use dataconnection, since it says it's possible
Without sounding flipant, the CAB is 1.73Mbs so I would expect it does not contain map data, bearing in mind that TomTom Maps are in the region of 1Gbs.
Maybe you have to download from somewhere else though.
<double post>
The map are downloaded using Data connection, they are download on demand by the software.
Google Navigator
the meaning of offline Navigation in this Software is that you can specify an interested area and tell the program to download the related topo, road maps, etc to the device over a data connection at a a given Zoom level. (wifi or gsm)
once the download is complete you can switch off the data connection or remove the sim and use the application to locate/Navigate your self in the downloaded area. The purpose is to enable you to use the phone to navigate yourself in a area without network coverage and/or to cutdown on the data download cost over GSM.
FYI
Google Navigator works fine on the HD except for the 3D view. it creates some areas of the map to disappear. I wrote to the developers on this bug and they said they will correct that error in their 4.9V but till the latest version the problem is still there.
is it just me or is the trial version of this completely useless? what is the point in disabling the only features that actually make this different to google maps? surely a time-limited version rather than feature-limitedwould make more sense?
I for one will certainly not be shelling out for this unless I know it works (and on my phone too).
this is most unlike google, who's software (until now)I have always been most impressed with. google maps is simply phenomenal, but does lack the turn-by-turn voice commands necessary to operate it whilst driving.
the data, for me (and many who own this type of device - why on earth would you have a device this capable without some data included?!) is not an issue. but i need to see it in action before I can abandon Tomtom properly...
is this software actually from google or just based on google maps? I still can't work out why I have to pay for this when everything else google is free (and this looks decidedly shoddier)?!
kindregards

Apparently Google Navigator has nothing to do with Google. The developers are just using the name "Google" because it taps into the Maps database. Caveat emptor.
Google Navigator is one of the worst PDA Apps I've ever seen.
Not only do they #1 -- Use the FREE google maps service, and charge you for their crappy front end, but #2 -- Put the name "Google" in the title of their product, so you think it's actually from a reputable source.
Google really needs to put a stop to this company because they are basically ripping people off.

UnIdentified Headunit

Hey everybody,
I've got an unidentified android headunit installed in my car,
I've been trying to figure out what brand it is ,and if possible i'll update to Kitkat.
Up until now, it seems to look like Icartech s730, but there are few differences between them.
I've searched on the internet few like the MCU version and the kernel version, but I've got nothing out of it.
here are the details:
Uboot version v00.01.13
Kernel version V24.02.25 20140930
OS version Android-4.1.1 V1.01.75
MCU Version V0.60B
I've also attached a photo, there are 4 soft keys (eject, back, home and volume), and a USB port underneath them.
Thanks
have the same
Hello
i have the same head unit & its Symphony SYD-70 BTWi
but as you said it has nothing on the internet related
& the icartech is the one that looks exactly like it with the look difference only
and i bought it from Egypt
I can not find anything on line about that system
where I bought it they say that it is called "TARGET U-1001" (some call it "i-1001" or "android i-1001)
got it as "closed system"- can't install apps. google play is not shown on screen
when I open the browser on this device and going t google play, it starts downloading apps but refuses to install.
does any one know how to hack it so it will be more useful ?
please contact me : [email protected]
thanks

I have the same unit, I did manage to access google play and install apps through it.
Does your steering wheel control work? Mine doesn't get anything from the controls, even when trying to re-assign them.

Joying 2GB Sofia for a Chevy - LIke it, want to love it

I recently purchased and had professional installed the JY-CL001N2. I like the unit but I feel with the potential it has I could love it. Here are my issues:
1. When I start my vehicle it takes 10 minutes for the GPS to lock. By the time it does, I am almost to my destination. Is there a way to speed that up? I am using GPSLock because once it locks on the signals it, I can tell it what GPS program I want it to open which leads to my second issue.
2. I like using Google Drive. I know that it is Google Maps but with Google Maps you have to select the location or select Drive. Why can't I just select drive. I know where I am going. I just like to use Drive because I can get real time traffic.
3. Since Google Maps does not support speed monitoring I am using Maps Speedometer which I like. It created an overlay on Google Maps and lets me know what my current speed is but I can't get it to open when Google Maps/Drive opens even though I have set it to do so.
4. Is there a way I can set what apps I want to open on startup?
If anyone can offer insight to these issue and/or ways to resolve it, I would greatly appreciate it. Thanks.

HengCheng PRO s9

Hello,
I recently purchased this unit:
https://www.aliexpress.com/item/1005001723766214.html?spm=a2g0s.9042311.0.0.52f54c4dcVJLhn
The install was a little difficult but went okay. For some reason when I try to login to login to google playstore it automatically closes. I have tried allowing app permissions and clearing storage and cache. It says it is running Android 10 API 29 (qp1a.190711.l020). It has carlink installed but does not seem to recognize my phone. I have managed to get the Bluetooth working, but I guess I should have done more research and gotten a unit that other people have. Do I risk bricking the device if I try to flash another version of android onto it? I like the DSP and some of the features but I can't even log in to google. Also could someone tell me if this is MTCD or the other? The company is responding to my questions so far but it was really late in China when I told them I can't log in to google, so hopefully they message me with a fix tomorrow. There seems to be 4 instances of an app called "Launcher 3" and an app called "App store" that says it could ruin my device if I try to uninstall so I just disabled it. This thing seemed to have all the features on paper, 8 cores, 128gb ram, 4gb rom, DSP, dash cam, rear view cam, optical audio out, 4g antenna, external sim card, gps antenna, 5 g capability... you name it. They "accidentally" sent me the 64 gb version instead of 128gb but they sent me a free dash cam and tpms to make up for the mistake (which they denied at first). If anyone knows why google would be doing this and a fix please let me know. Big let down for 450 bucks.
Please post a picture of the system about screen for your unit, that would help determine if it is MTCD/E. You should be able to find such a screen in the settings.
You're pretty lucky that they're responding to your inquiries. There is a chance that your head unit is not running Android 10 and may be fake in many regards (e.g. running much earlier version and "claiming" to be Android 10)).

Thank you for the quick response. Yeah, at least they are responding. If you click the add it looks so legit with the 8 core 64 gb 4 gb ram. But my home screen looks nothing like what they advertise.View attachment Home screen.webp
Please scroll the view up on the about screen and take another picture. It is hard to see with what looks like plastic film on the screen. Would like to see the MCU version and perhaps additional information. Thank you for posting the first picture.
Oh and my pleasure to try to help you. We need to determine for sure what the head unit is and if it's MTCD/E I along with others here in the forums would be glad to try to answer your questions and help you resolve the issues you're having.
Sorry it's super bright out. Here ya go.
The only units I could find that use that particular CPU (UIS7862) are Joying branded head units. Their units are not MTCD/E. That being said, this thread probably should be moved to Android Head Units as the discussion in that forum are for non MTCx head units.
I will offer you this suggestion regarding the Google login issue, try opening the YouTube app or Google search app and try logging in from one of those. Alternatively locate the Accounts section in the settings and see if you can login to Google from there. That may help with the Google Play launching issue. If you can get GP to launch then you will be able to get Play Services updated and other applicable updates to make the Google apps/ecosystem work.
Once you get Google Play working, I would suggest installing an app like CPU-Z to see what your system consists of.
One more thing, welcome to the XDA community.

For sure, I have heard the Joying are decent. I haven't been able to get it to interface with my phone other than viewing it as files. I cant do the mirror screen split screen that is advertised in the AliExpress ad. I tried to download Zlink apk and install it (disabled third party app restriction) and it said not installed. Maybe I need an older version than 4.0.6? Unfortunately none of your tips worked, even the google one, but thank you so much for taking the time to assist me. Hopefully the seller has a fix for this, as I am not great with android.
Requested via report to move to Android Head units forum.
Sorry that my suggestions did not work for you. I have asked the forum moderators to move this thread to the Android Head units forum where maybe someone in that forum maybe has experience with the same or similar head units as yours. Suggest searching the forums here as I'm confident that somebody has solved the Google login problems you are experiencing.
Your head unit should just work out of the box. I would not recommend updating firmware or such major changes before getting your unit working at a minimum as you expect. Thing with that is how will you know if additional problems that you might encounter are from the update vs what you have now?

Already done same before. Thank you.
By selecting one of the variants of launcher as the default launcher app you should be able to get the user interface to look as shown on the ad where you bought the unit. Since these devices are sold under many brand names, they often include many different launchers which is what provides the user experience seen when the system boots up.
You should find a default apps selection in the settings where you can pick the default launcher.
One more suggestion that might get it where you can login to Google would be to locate the factory reset option in the settings. Since you couldn't install any new apps on it anyway, not much to lose customization wise.
I believe there is a system patch for the FYT IS7862 units. My IDoing came working so I assume it was already patched, but if you head to the Joying thread you'll see posts about a system patch. Not sure that patch will work for your unit, I think that's what you need.
Actually, they are being pretty helpful. They just sent me an update I have yet to install (kind of afraid as it is working now and I realized I don't really need google integration. Here is a screenshot. Good to know it is a FYT IS7862 unit.
Here is the new firmware she sent me and instructions. Honestly kinda scared. She didn't tell me what I am upgrading to, she just said new version. Maybe someone could check this RAR out if they have time?
https://wetransfer.com/downloads/2f...6e4ab0a57f920b634846c7f920210515022252/aac7ff
Just for fun I went to the download page and did a screenshot of the page. I then ran the screenshot through the Google translate app. With the transition set to go from Chinese to English, the download link says "overseas system. rar".
You could possibly run the PNG file that you attached to your post thru Google translate and maybe figure out the filenames. The picture is not clear enough to do the same as the picture resolution is pretty bad. Was hoping maybe the download filename would offer some clues about what the rar file contains.
Maybe you could request from whoever sent you the link, an English version of the download if available. Granted they say something about English text showing up in green after the flash. I could totally understand your apprehension since you cannot read the filenames.
I could unrar the file and try getting filename translations, might be helpful.
Man, I really appreciate you looking into that for me. I went ahead and bit the bullet and did it and it booted up with a different theme and reset to factory settings. Seems to be dropping my home wifi connection now. I havent tried putting a sim card in the unit yet, as I only have a micro sim from my tablet. I asked her several times what we are upgrading and she said it's not the android version, but a fix to make google login work. So, I went to login to google and instead of getting hung up and crashing after the "checking info..." screen it actually had a box to type my gmail address and let me type it and press login. Then it said "Cannot contact google servers, try again later.
This 1.4 GB file seems large for a small fix. There were like three ZIP files in the rar. Also, when I look at what is using memory on the unit there are like 10 apps I didn't open in the background. Makes me feel like the mfg. has some spyware or malware on the unit. Isn't it commonplace to completely wipe one of these units clean and install a different version of android? Why couldn't I just install android 11? Is it becasue I wont be able to find the apks for unique apps and functionality on there?
They usually (never) provide system patches that fix one specific thing. By providing the whole system update it still makes it impossible to know exactly what's being installed.
Unfortunately it's not so simple to go from one version of Android to another as they intentionally make it difficult to do. It kind of puts a lifespan on these units. There's always gonna be something broken or something that will eventually break rendering the unit useless or just be a flaw that you end up accepting. Plus by limiting the Android version its planned obsolescence as updates won't always be available forever.
Maybe and it's a big maybe you can find an alternative ROM for your particular system right here on XDA. Those are becoming more and more rare because of numerous factors however.
I wouldn't recommend logging into the head unit with a Google account that has a payment method associated with it. Maybe create a whole new Google account just in case? Also you could try going somewhere that you can get free public WiFi (e.g WalMart, McDonald's, etc). All that would do is confirm it works, for what it's worth.
Regarding the wifi connectivity issue, was it able to connect to the same wifi before applying that provided update? Is the wifi signal strength good? It's likely connecting to the wifi but not getting an IP address and other connection parameters and disconnecting on failure. There is an advanced workaround that involves manually setting the network connection parameters (e.g IP address, etc) but you'd need to be comfortable with doing that sort of thing. Let me know if interested.
Despite the update essentially doing a factory reset as part of the firmware installation, I suggest manually doing a factory reset. Maybe even do the reset a couple times just to be sure. Truth is that the device should just work out of the box without the extra contortions.
Apparently the Google login problem is a common issue and there are claims of Google hacks on these units as well:
Post in thread 'New Joying Android 10 UIS7862 Octacore 1.8GHz (4GB RAM, 64GB flash)' https://forum.xda-developers.com/t/...8ghz-4gb-ram-64gb-flash.4168069/post-85003075
I was looking at one of these on Aliexpress and found this thread. @CaliBurr, do you have any updates on how this is unit is working out for you?

Android unbranded for car lost Zlink

Hello all,
I've just got an Android unbranded tablet for my car (BMW E82) yesterday.
It's a 10.25 touch screen with Android 10.
Under System Information, I can read: version HY: V2.32.4core.201113.
I can enter to factory settings via 8888 code.
It came with Zlink already installed, and I could make it work perfectly yesterday with my iphone & wireless carplay.
(I can't remember actually if it was Zlink or Zlink5 but it worked good).
Today, I mistakenly cliked on reset to factory, and after the headunit rebooted, the Zlink app is not present anymore.
I am struggling to get it back...
I have found some Zlink apk files in forums, but none worked for me.
Does anyone know if it's pre-installed somewhere on the head unit, and I just need to enable it ?
Or should I install it with an apk file ?
Thank you in advance,

i think you can find it in settings then in factory settings it might your factory setting have password 1617 or 2010 try any one of this password. there you will find the option name feature settings in there find “phone connected” or something like this tick that option and you are ready to rock again.

Hi Rooblevarn,
Thank you for your reply.
I tried the 1617 and 2010 passwords, but they don't work on my Head unit.
The only password that worked for me so far it's 8888.
I can then get into a factory menu as shown in attached picture.
I have looked everywhere in those menus, but I can't find anythink similar to "phone connected".
I suppose that Zlink app was installed manually by the vendor before he sold me the head unit, and the only way for me to get Zlink back, is that the vendor send me the file that match this unit to be installed....
Problem is that I don't have vendor contact.
I've been in contact with one of the vendors of an Android 11 HU I recently purchased,
#1 - It's tough to communicate with them
( they are all in China, and it's clear they translate English using Google-T )
I don't know the specific build for your system, but Zlink is somehow tied into the entire Android Build Version which they custom build for each HEAD Unit.
I have provided two different files here. READ this carefully.
The file starting with:
gongban_92_Zlink - is the older version of Zlink. It may be less resource intensive, but it works similarly to the new Zlink5 version.
The file starting with:
gongban_F92XX_Zlink5 - is the newer version of Zlink ( or at least as new as it can get) ( This was given to me by the manufacturer's tech dept in March of 2023. )
The way I was told to install these is to:
- Save which ever one you want to install onto an empty USB stick.
- DO NOT change the name or the extension of the file.
- Plug in the USB stick
- Open Your App Drawer > Find Car Settings > Find System Information
- There could be a button on that System Information screen that says: Android Update ( This button was greyed out(unaccessible) until plugged in my USB drive.)
- You hit that button and wait for the update to finish. everything is automatic from that point.
- When successful you would notice a new Zlink app in your app drawer. It might even automatically launch after system reboots.
BEFORE YOU GO TRYING THESE STEPS THOUGH:
Understand that these apps are custom built to access bluetooth and Wifi functions of the Android system.
If they are not installed correctly they might
A: Not work at all
B: Brick your device
Here are some photos of the specs of my device and some screen shots of how the settings pages look and where you can find update options (given you have the right update files):
How old Zlink app looks:
How new Zlink5 apps looks:
Settings Page:
and finally ABOUT FACTORY SETTINGS and your app disappearing:
When you hit Factory Settings ( and get into the main screen:
You should see an option called APPS:
When you enter that there could be a screen with the header: XYZ apps
XYZ apps is a custom system settings app which forces apps to boot with the head unit, and never allows them to force quit. ( This app in not attainable on the app store - is what I mean by custom)
Before you go installing any updates or files, find the APPS section in factory settings and see if Zlink is on that list.
The list is "check-able" - like toggles or check marks
- If you see the app there and it is UNCHECKED then CHECK IT, go back a page and find Reboot.
Then see if you app appears again.
If you don't see it.. well.. that's beyond my understanding, but most likely you would need to install them through a USB port like I detailed above.
Weather or not MY attached files will be suitable for your system is a whole other question.
One other thing:
- I'm not a developer and I don't know how build versions work on Android and how each aspect of each function affects other aspects:
But it is clear that the Chinese devs who write these Android builds are forcing certain apps to run in the background.
Having said that.
NEVER connect your Android head unit to Wifi and use it to access Personal Information or store passwords.
These aren't ATT or Verizon head units. They are made by a foreign company who is most likely under the umbrella of laws and regulations which allow the military to snoop on customer data in the name of the motherland...
The only way I use my headunit, is for it's radio, and the Android Auto function for navigation.. (whenever Zlink isn't crashing)
I don't allow any internet connection to the unit as it is not necessary. As a driver all you need in a car is a map and some tunes.

gongban_F92XX_Zlink5 - is the newer version of Zlink ( or at least as new as it can get) ( This was given to me by the manufacturer's tech dept in March of 2023. )
The way I was told to install these is to:
- Save which ever one you want to install onto an empty USB stick.
- DO NOT change the name or the extension of the file.
- Plug in the USB stick
- Open Your App Drawer > Find Car Settings > Find System Information
- There could be a button on that System Information screen that says: Android Update ( This button was greyed out(unaccessible) until plugged in my USB drive.)
- You hit that button and wait for the update to finish. everything is automatic from that point.
- When successful you would notice a new Zlink app in your app drawer. It might even automatically launch after system reboots.
BEFORE YOU GO TRYING THESE STEPS THOUGH:
Understand that these apps are custom built to access bluetooth and Wifi functions of the Android system.
If they are not installed correctly they might
A: Not work at all
B: Brick your device
Here are some photos of the specs of my device and some screen shots of how the settings pages look and where you can find update options (given you have the right update files):
How old Zlink app looks:

How new Zlink5 apps looks:

and finally ABOUT FACTORY SETTINGS and your app disappearing:
When you hit Factory Settings ( and get into the main screen:
You should see an option called APPS:
When you enter that there could be a screen with the header: XYZ apps
XYZ apps is a custom system settings app which forces apps to boot with the head unit, and never allows them to force quit. ( This app in not attainable on the app store - is what I mean by custom)
Before you go installing any updates or files, find the APPS section in factory settings and see if Zlink is on that list.
The list is "check-able" - like toggles or check marks
- If you see the app there and it is UNCHECKED then CHECK IT, go back a page and find Reboot.
Then see if you app appears again.
If you don't see it.. well.. that's beyond my understanding, but most likely you would need to install them through a USB port like I detailed above.
Weather or not MY attached files will be suitable for your system is a whole other question.
One other thing:
- I'm not a developer and I don't know how build versions work on Android and how each aspect of each function affects other aspects:
But it is clear that the Chinese devs who write these Android builds are forcing certain apps to run in the background.
Having said that.
NEVER connect your Android head unit to Wifi and use it to access Personal Information or store passwords.
These aren't ATT or Verizon head units. They are made by a foreign company who is most likely under the umbrella of laws and regulations which allow the military to snoop on customer data in the name of the motherland...
The only way I use my headunit, is for it's radio, and the Android Auto function for navigation.. (whenever Zlink isn't crashing)
I don't allow any internet connection to the unit as it is not necessary. As a driver all you need in a car is a map and some tunes.

Thank you for your reply ! It helps to understand a lot of things.
Well, today I went back to the (physical) shop where I initialy bought the device last week.
I told them that Zlink is no more available and to me, it's the most important feature on the tablet.
They tried to reapply a new Reset factory settings, expecting that Zlink will be back with that, but it wasn't back. As they couldn't find a solution, I asked to replace the HU.
At first, it was a 2/32 GB (Android 10), and they replaced it with another with 8/64GB (Android 11) from the same manufacturing (on the box I can read J-1018)
Wouah ! Now it makes all the difference !
The device is much faster, and now when I go to factory settings (with 8888), I can find there a menu, like the one you are mentionning, called in my device "Type selection" as seen in attached picture.
This menu was not present in the previous 2/32 GB device...
Now as per the seller, even if I hit on Reset factory settings, I will always have the ability to restore Zlink (which a built-in version, quite old as it is 3.8.8 but it does the job).
I think we could have found a solution on the 2/32 GB (Android 10) with the help of your files. But I don't have anymore the device, so can't test it.
I hope someone else from the forum with the same problem can test them, and reply back if they are helpful.
In all cases, I am happy that this issue occured on the first device, because thanks to that, I have now a 8/64 GB instead, and I can only recommend to anyone buying a new Android HU, to choose as minimum 4 or 8GB of RAM, and 64 or 128 GB for stock memory. It is the minimum nowadays.
