Does any body know whether android head unit can control the car CD changer or not?
I suppose that there should be extra wirings for it but could be that someone has already an idea.
no

Hi, I am looking to buy a new double-din head unit for my car. I was wondering what the best way to mirror my s6 edge to my car and basically controlling the phone through the head unit using touchscreen? i want to be able to use google maps on my head unit. Should I be looking for a head unit that is mirrorlink ready or am i looking for a head unit that is compatible with chromecast (Pioneer's appradio from what i've read)?
Welcome @hackaveli, you may want to take a look at this thread: http://forum.xda-developers.com/showthread.php?t=2451980
There aren't going to be many options to control too much of the phone via the head unit, unless you're talking just using BT to control synced things like the phone, and streaming radio. AppRadio aside - if you do find android-based head units, or at least head units with app capability, that are wifi capable, and if you have a hotspot feature on your phone, you could do that, tether the head unit to your phone to access the data for your Google Maps and whatnot.
All that aside, I had a 3-series that I put exactly that kind of aftermarket head unit into. And after the initial play factor wore off in a month, I used exactly one of the fancy options on the head unit - Pandora. I would tether my phone, and start the app. And that would've been just as easy to bluetooth the phone to the HU for sound instead of running it from the unit itself. I just found that it was much easier to just do maps on my phone (my mount was vent-mounted so perfect viewing angle and reach), as well as any other things that I THOUGHT I wanted all those goodies on the head unit for. So obviously your mileage may vary on that.
Hi all,
Anyone know anything about how exactly do the head units communicate with the head units?
AA doesn't have keyboard control in the standalone version, and I'd like to see how the keyboard control works in the headunit version, to see if I can replicate similar functionality.
Any other info on AA hardware is also welcome.
Have a look at https://github.com/mikereidis/headunit
Its an open source implementation of the AA headunit part
Hi, I've recently bought a used car and installed a Xtrons PE98MTVPL on it.
Now I have discovered that the used car has TPMS sensors installed on the wheels. What would I need in order try and see if these work with the head unit? Do you need some additional hardware or can I pair the sensors with the head unit as default?
Best regards
David
You need an add-on USB device for TPMS like this: https://www.ebay.com.au/itm/USB-Car...ystem-with-4-External-Sensors-AU/263958460650
First thing you need to know is that there are two main frequencies used, so you would need to match the unit you buy to the frequency used on your wheels. Also I have no idea about compatibility across manufacturers sorry.
Hi,
I have a 2015 Audi A3, which unfortunately didn't come with AA as an option (I think it was introduced in 2017). It's a real pain to install the 2017 MMI into an older car, but there are guys out there developing aftermarket Android-based headunits that basically put a whole android "phone" in the dash; which isn't a very eloquent solution and kind of overkill in my opinion. They've got their own SIM cards and you have to change the bluetooth devices the phone is paired to and whatnot. It's really not exactly what I'm looking for. I just want AA and that's it.
Anyway there's one guy who's kind of got what I'm looking for . Unfortunately because the car also didn't come with a touchscreen, I have to toggle through the menus with the knobs and steering wheel buttons, which is meh. I'd love to put a digitizer overlay on the screen and play around with it, maybe have a daughter board made up and inject the screen coordinates into the packets somehow before it's sent down to the phone. I'm more of an EE, don't really have a lot of Android dev experience but I've got a lot of microcontroller and firmware experience. Anyway that's my high level idea of how this might work, not sure if I'm going in the right direction. I did ask the guy at RSNAV (seems to be a one-man show) last night if I might have the source code after signing an NDA and I'm awaiting his response. In the meantime I want to get a plan of action going.
So I'm wondering how AA is integrated on the client-side. Obviously the manufacturer headunits aren't running Android, but they've gotta communicate somehow with the phone. I can't find this info anywhere, I'm guessing this is info Google only shares with Auto manufacturers and the Kentwoods and Pioneers of the world. But maybe I'm wrong. I'm assuming it's a protobuf-based protocol between the headunit and the phone, but I don't know.
Can anybody help me out here? Thanks.
All my android auto head units are running android operating system two Chevy and one Mitsubishi. Main reason why poplar cars get rooted head units and what not. But after market android auto head unit is probably your best choice.
Hi guys, I am new to programming and classic cars. I recently have the chance to buy a 80 model toyota and decided to make a head unit with my old samsung S3. I won't use it to control music or make calls. I just want head unit to show temperature, compass, fuel level etc. By the way, car does not have OBD or ECU, most of the reading would be analogue or through new sensors. Is it possible to attach new sensors to my old phone and read results on the screen? I believe this can be done using a raspberry pi but I am on a tight budget and if I can use what I have at hand for this project it would be really great. I add a sample image of what I have in mind to build. I want it to look genuine and proper for a classic car. Any help is greatly appreciated and I can even offer a test drive with my old beauty if you happen to swing by my vicinity
buy a Bluetooth odb2 adaptor and use the torque pro app.
I simply do not have anything to connect to OBD all the readings regarding the car are old fashion analogue. there is no central command or control.
yeah I forgot about the "classic" part. My bad. Torque will still let you use your phone sensors, so gps speedometer, and gyro based drag timer and hp estimate, but I dont know of anything else you would be able to use. Not that something doesn't exist, I just dont know what it would be.
thank you man I guess I will use the app and look for temperature on my phone.
When did 1980 start being classic, I was thinking pre-70 at least. Which model do you have? I'm trying to remember if the standard DIN size was being used then - I know it was on my mid-70s VW, but that was German, which is where the DIN came from in the first place. Dropping in a 1-DIN android head unit might be easier that rigging up something with your phone.
