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!

Has anyone used something like the Delphi Connect or Zubie with their head unit?
I just picked up one of the new Lollipop units from Joying and would rather not connect it with my phone. I am looking at these OBD units vs a USB hotspot. While I would give up bluetooth for OBD, I could run the Delphi or Zubie app on the head unit itself and see the diagnostic codes, etc.
Any experiences or thoughts? Reasons to go with one over the other?
Thanks!
I installed my new head unit today and picked up a Zubie from Best Buy. It is a hotspot that plugs into the OBD port.
It works like a champ too.
My head unit connects via WiFi and I have an always-on connection regardless of my phone being in the car or paired. This saves my phone battery when streaming music and running Waze (which is pretty much the entire time I am in the car).
I haven't even paired my phone to the head unit and am not sure that I will.
I can't run Torque since the OBD port is now in user, but steering wheel controls seem to work fine via CANBUS, so hopefully it won't be a problem.

First of all. I allready use torque and a obd2 adapter, but my old car dont give much information via this port.

Is there any gauges that can comunicate with my android head unit? Like turbo boost, exhaust temperature, transmition etc....
Would be nice to get this jnfo in my head unit, instead of extra gauges .
New to forum, as well as new to the Android, Android Auto head units
I am looking for a better understanding of what's needed exactly to display the 'Torque Pro' app directly to a 'Head' unit without passing through a third device
I have the scanner port device
I have the 'Torque Pro' app running on the s9+ mobile device
Goal is to have the app running on a head unit minus the s9+
I have been reading, researching
Down to a Sony Android Auto unit
Or
Joying head unit that uses a sim card?
I am also concerned about quality of music playback, radio and FLAC files
Many thanks for your thoughts
To have OBD directly your only option is an Android based unit like the Joying. Android Auto just mirrors certain apps from your phone.
You'll need an OBD2 dongle. Just install Torque on the head unit and link it with the dongle same as you would with an Android phone.

Would this obd2 dongle be a USB, Bluetooth or WiFi connection?
I'd still want to be able to connect to phone to the head unit for calls etc. But for the torque Pro to work without the phone.

Yes, Bluetooth connection from head unit to OBD II adapter. You can have multiple Bluetooth connections so your Anroid head unit will be connected to your phone for voice and media and the OBD II adapter for data.
Hi,
I have bought the following Android head unit and I'm happy with it so far. *edit* I can't post links yet. If you need the link to device please let me know
The unit is made for Audi A6 models and came with a pre-installed launched called Audi-Launcher (what's in name? ). The thing is the launcher shows my speed, mileage and temperature on it's dashboard and the data is coming directly from the CANBUS i assume.
What I would like to know if it's possible for Torque to read out my car's data in the same way so I do not have to use an OBDII adapter. If so, how do I configure it?
Any help is much appreciated.
Cheers!
No, Torque cannot read the canbus info from the HU adapter, only via BT or WiFi from the ODBII dongles.
I have a similar setup and need to turn on the ODBII adapter for Torque to read any information, despite the HU having access to car data through its own adapter.
I have the above head unit fitted and working fine in my car but I have an engine management device that contains a bluetooth low energy module in it. I would like to connect to this module via the provided app however it appears my head unit does not see or connect to BLE devices.
Does anybody know of a USB type device that I can connect to the head unit which will provide the ability to connect to BLE devices?
I'm using standard Dasaita android 10 and 3.69C.
Thanks
I have a similar issue. I have an Axxess signal processor which you make adjustments to it through Bluetooth. The processor connects to my phone but won't even be seen by my head unit (Dasaita max10). These head units only seem to recognize a phone or (select) obd dongles. It's pretty basic. I have been looking for ways to expand this, but so far unsuccessful.
