I have a turbo Corvette and am looking for a clean way to display boost pressure (PSI) and air/fuel ratios, and maybe more parameters ( like fuel pressure) without installing tacky looking gauges on my pillar or dashboard. I decided it would be a good idea to display them through a Android headunit as it'll offer a clean look, room to grow (won't need to buy more gauges for additional parameters).
The information will go from sensor > controller box > bluetooth OBD2 adapter > headunit (via bluetooth).
I will need almost instantaneous information so I can catch something quickly if it goes wrong.
Would this be a good idea or should I stick to gauges?
If you're curious, this is what I am planning to use to transmit the data: http://www.plxdevices.com/SM-AFR-Gen4-Wideband-AFR-with-MultiGauge-Link-p/897346002870.htm
I use a setup for this in my Mazda, Bluetooth OBD to my eonon headunit using torque, the response depends on the adaptor and the ECU, so in my case it's fast enough with sub second refreshes depending on sensor. RPM, A/F, fuel rail pressure, etc are instant. Coolant is per second refreshes.
I'd use it with my Supra but the aem infinity doesn't have an OBD port so I had to go a different route.
I'd pick a USB OBDII reader over BT. You could always try it first on a phone or tablet and see if it meets your needs - the bottle neck will likely be the ECU itself (or how frequently it outputs data to the OBDII port) or the OBDII adapter not the Android device.

This unit is the same as pumpkin RQ0255 unit. There is more information available from their support page and is directly applicable to the Naviskauto unit you have.
I installed this unit with a Metra dash kit into a 2003 G35 Sedan with Steering wheel controls (kit required) / the stock Bose amplifier (audio interface kit required) / and reverse Cam. All the functions you want are available. I assume you want to connect iphone/ipad via bluetooth , it works but the bluetooth interface for music isn't great , and maybe a 3rd party app is available. There is an "IPOD" USB connection through a 30pin connector. (Overall, music quality is very good but not as good has name brand head units for USB/Bluetooth/Radio. ) I use an Iphone 4 as an Ipod over USB, but you should be able to use a lightning convertor cable and use newer iphones/ipods. The music interface is better on USB but still falls short if you're looking for iphone/ipad useability. You can connect the head unit to a wireless hotspot on iphone/ipad or any device with this function. You can also connect via USB to a 3G dongle but the supported devices are limited, (more reading for you.)
GPS works great and the iGo Navi app provided is really good and does not require an online connection. You may need to do some more reading to get maps / poi functioning to your needs depending on your location.
It's my first android head unit install and it was flawless for me. I invested lots of time reading to extract experience from this board and others I am generally familiar with car sound systems, electronics, soldering so I was just a matter of understanding the wiring interfaces for this unit, which are standard.
I'm a newbie on Android , so I'm not experimenting with ROMs yet but there is a ton of info on what is possible with mods and replacement apps for various functions.
so, bottom line, I give the unit a 8/10 overall, but the value for money from Amazon I give it 9/10.

Thank you for your information.You're more experienced than me as I can tell. According to the review,it seems a good choice.I will look at more and make a "experienced" choice,I think.thanks again,man.:good:
Hello everyone,
I am planing on inserting an Android 9.0 head unit with PX6 into my Merc CLK (209 series from 2004), but unfortunately Mercedes made damn sure to make life as unpleasant as possible if you want to tinker with their fibre optic D2B Bose System. So in order to get any sound with the built-in Bose speaker system you have to stick to their dated radio equipement with fibre optic capabilty. I don't wanna rip out the whole Bose System at this point and converter boxes only exist for M.O.S.T devices which followed after D2B. Fortunately you can modify their smallest D2B radio with an aftermarket Bluetooth chip and give it some modern day connectivity. And this is where my question comes into play:
Is it possible for those Android head units to send audio "outwards" via bluetooth ? The main idea is for the Unit to stream it's audio signal (like an ordinary phone or tablet) to the Merc Radio, which will be hidden in the glovebox, consequently acting as an "external bluetooth speaker".
And if it's not possible for the head unit to do so, can they be modified / adapted with a dongle, etc. of some sorts to transmit bluetooth? Creative constructive suggestions are very welcomed here. The ideal constellation would be in the end: Phone/OBD2-dongle/etc. connected to radio connected to Merc Radio Bluetooth receiver. So multiple bluetooth connections should co-exist at the same time.
I know I am probably asking for a lot here and I am of course willing to take cuts, so the most important feature would be for the Head unit to emit all its audio signals to the "Merc Radio bluetooth speaker".
So any pieces of advice from the experts here would be very much appreciated! :fingers-crossed:
Best regards,
Alan
Is the fibre optic system SPDIF / TOSLINK? There are head units that have SPDIF out (Joying, via Coax - but you can convert Coax to TOSLINK easily).
You can also get USB SPDIF but they seem hit or miss. Depends a lot on the version of Android you use, and some will not allow OS to control volume, etc.
To answer your original question - seems like my head unit only acts as a bluetooth server, not client. It cannot connect out as you are asking.
I am in a near-identical situation as you (2003 Sl55 with d2b Bose system). My current plan is to run the audio coming out of the android head unit into an RCA to AUX adaptor, which then plugs into the aux input on my command system. The command will be relocated to the boot and connected to the Bose amplifier over D2B.

Hi Rewen,
unfortunately no. It's a proprietary Mercedes System which was not Used anywhere else in that form (at least to my knowledge). It was changend to M.O.S.T in 2004/2005. So Support from third party developers is basically non existent. If you do research on that topic you usually come to the conclusion "stick with it or exchange the speakers, amps, radio....alltogether. It's not the best sounding system to be honest, but for now i don't want to put up with the hassle and the cost of a complete good quality car hifi system.
Thanks for you info, i guess this will account to probably all head units, so i will just stick to a transmitter dongle in the back of the head unit then. That should do the job.

Hi joe,
SL55? very nice choice!
After all my research so far i think the Aux cable / Bluetooth dongle method is the most "acceptable" solution for any D2B owner who wants to stick with the Bose system but also wants an android head unit. I was also thinking of just using an Aux cable (Have the Comand 2.0 with AUX), but i ran into a lot of interference noice with the cable, therefore i was driven away from that idea. That's why I will just get a used Audio 10 CD with D2B, modify it with bluetooth and replace my disc changer with it. This will hopefully spare me from running any cable through the car....(too lazy for that right now^^)
All,
I have two of these in my commuter cars. (2007 Saturn Ion/2001 Impala)

I commute around 100 miles a day.
I have been pretty happy with these Binize especially for the price point. I have a rear camera on both.
I use it daily for GPS, radio, my playlist (on thumbdrive), and Podcasts (Stitcher). I expect them to be a low end GPS tablet with an amp and they do that. I also have a ELM327 and the Torque app installed on the head unit.
It took some trial and error to get everything setup software wise and I was meticulous on the wiring (soldered connections/heat wrap/full install kits etc.).
They have been installed for over a year now.
Anyways I have decent size fingers and the side of the screen volume can be tricky especially in the Saturn. So I picked up one of these;

The Remote Control unit pairs fine with my Samsung Note S10+ cell phone. It adjust my cell phones volume well and does what it should . The head unit under the Bluetooth icon under AGAMA sees the X09 Bluetooth device but does not Pair as my ELM327 does. I have deleted the ELM327 out of the Paired Devices to see if that is the issue but to no avail.
Is there any application I could download to see what is going on. Is this a issue with Android Head Units?
Are there better Remote Control Units out there to consider?
Also while we are discussing Android Head Units. What Applications or hardware do you have on yours that you find interesting?
Thanks
Chris
Included is what I am seeing...
I have same approach to those head units - low end tablet with BT, gps, mp3, video and reverse cam cappabilities.
But according to your problem with BT connection. Im not sure if bluetooth in those radios is fully functional as in other devices (for transmit files, tethering internet etc) or its just like head set - limited capability only to hands-free talk via cellphone.
But if you use it with ELM (or other CAN decoder), than it should work with SWC also...
Maybe try without Agama launher? Use stock software for test
I think that there are better options for steering wheel control. At the back of your radio there should be two additional wires, marked as KEY 1 & 2. They are designed to be used with resistance-based controls.
Do a refund with that you already have (with BT) and buy this:
https://www.ebay.com/itm/Remote-Control-Button-Car-Audio-Steering-Wheel-Wireless-Bluetooth-Universal/302763993342?_trkparms=aid=1110006&algo=HOMESPLICE.SIM&ao=1&asc=225074&meid=f4ff115cb3864f40aac6e56b787db63c&pid=100623&rk=5&rkt=5&mehot=pp&sd=264013200753&itm=302763993342&pmt=1&noa=1&pg=2047675&algv=DefaultOrganic&brand=Unbranded&_trksid=p2047675.c100623.m-1
or
https://www.ebay.com/itm/Universal-...rand=Unbranded&_trksid=p2047675.c100005.m1851
But before that make sure that you have key1 & key2 (or SWC 1 & 2,)
It also uses BT communication, but not this one in head unit. It has own BT module which you solder to harness and sends resistive signals via key 1&2 wires.
Personally I dont use wireless steering wheel control, but instead i bought controller like this
https://www.aliexpress.com/item/32997030091.html
cheap, reliable, easy to install and doesnt require batteries to run.
If you need more buttons you can install the second on other side
here photos of my bmw x5 01.
So I bought an aftermarket Android head unit for my car.
I wanted to connect OBD diagnostics apps for vehicle status info, but I had no luck.
I am completely new to this and obviously clueless, but from what gathered online I need an OBD adapter (wireless or bluetooth) to connect the head unit with the cars ECU. That would make sense if the head unit didn't already come with an inbuilt '' Car Info'' app that somehow accurately displays engine rpms, battery voltage, residual oil, mileage, etc.
Is the head unit somehow already connected to the OBD port or am I completely missing something?
The headunit offer you the possibility to read OBD information, but from where ? If nothing read the car information, your radio read nothing.
So, go and spend 10$ for an wifi or bluetooth OBD device, attack it to the car socket, open your BT or WIFI on headunit, do the connection 8PASSWORD 0000 OR 1234) and after that open the app to read the car information.

If your head unit comes with a can bus box then it will supply a (limited) amount of engine data.
Of which if the many types of head unit do you own and how/what was connected
Minus 10 points for posting a meaningless model number

Hi there!
It sounds like you're having some trouble connecting your aftermarket Android head unit to an OBD diagnostics app for vehicle status info. From what you've gathered online, you need an OBD adapter, either wireless or bluetooth, to connect the head unit to the car's ECU.
However, you mentioned that your head unit already has an inbuilt "Car Info" app that accurately displays engine RPMs, battery voltage, residual oil, mileage, etc. This raises the question of whether the head unit is already connected to the OBD port, or if you're missing something.
As someone who has built a Custom Raspberry Pi Car Computer, I can tell you that it's possible for an aftermarket head unit to have an OBD connection built-in, but it's not always the case. It's also possible that the "Car Info" app is displaying information obtained through other means, such as the car's internal sensors or third-party APIs.
If you're still not sure, you could try contacting the manufacturer of your head unit and asking them directly. They may be able to provide more information on how the "Car Info" app is obtaining its data, and whether or not it's connected to the OBD port.
In the meantime, if you're interested in building your own car computer, I came across this helpful guide that you might find useful: https://www.autopi.io/blog/build-a-raspberry-pi-touch-screen-car-computer/. It includes step-by-step instructions on how to build a custom car computer using a Raspberry Pi and a touch screen display. Good luck!
Want one with built in GPS chip, can take the abuse of a off road 4x4 , Has at least a volume knob.
It has to be mounted securely it can't float like the ones I see. I'll be adding apps for navigation, engine monitoring , camera inputs at least 2ea etc.
Outputs for a Amp, wifi for phone and usb for a I pod. Cell chip?, Plus non can bus.
Ideas?
Thanks
