Load custom ROM to proprietary OEM head unit, possible? - General Questions and Answers

My Toyota comes with an OEM Pioneer head unit: huge 9" inch capacitive LCD, no physical button, and it runs linux-like OS called iAuto 14CY, with its own app store that only has 21 apps.
What are the chances of loading a custom Android ROM onto it, and use it like a tablet? Despite its smart look, It has zero integration with the car ECU, and no car settings can be set from this unit whatsoever.
I have since replaced it with an android head unit, so I can spare this HU to experiment with.

[Q] What tablet, droid system for car infotainment

Hello all.
I have looked around via the search tool but not found what I was looking for directly.
Background:
I have a sterling kit car. I am modernizing the entire car to look, act, and drive like a modern day exotic sports car. So of course I would want an in dash infotainment system. However this car is extremely small. In fact the roof is only 40 inches tall.
So after remodeling the dash I have room for a 5 inch tablet. I would like to use an android based tablet, but most of the units I can find are chinese, and Win CE 6.0 based.
Im looking for the following features:
Google maps 3D GPS/Navigation
Bluetooth for phone, camera and OBD2 system access
WIFI
Back up camera wireless
Driving rear view camera
OBD 2 bluetooth system access
FM radio
MP3 Play back
Parking radar system
HD quality touch screen
Auto on and off based on external voltage (accessory power)
Custom boot screen and animations
I know some of these would be add ons and not part of the base android unit. But I am finding it very difficult to find a 5" tablet I can use in this way. It would be mounted in the dash board with only the screen exposed.
Can a win CE based tablet be converted to run android?
Im looking for a believable OEM in dash infotainment system. SI would imagine the processing power should be pretty good for fast switching, and animation speeds.
Thoughts? Ideas?
Thanks in advance!

Headrest zone with an Android head unit (Joying EU-JY-UO135N4GS in particular)?

Hi,
I may buy a Joying head unit EU-JY-UO135N4GS but I still have something unclear in my mind. Do Android head units support dual zone where you can see navigation on the head unit while listen to music or radio from the Headrest Monitor, you can see navigation while back-seat passengers can watch a film on the headrest monitor (my old 2014 Samsung Galaxy Note 10.1" in my case).
I mean how can you push a film with its sounds to the back zone of the car? Even if I had a real headrest screen with RCA input (which is not my first intent given I'd like to recycle my tablet), how does it work?
And trying to avoir RCA wiring, can I create a WIFI hotspot from the head unit then connect my tablet to it to retreive films and musics?
I may not be clear here but could not find related post on XDA then come to you,
Thx.
Anyone sotring films on the headunit and having children watching films in the back of the car? Which set-up?
Thx

Android head unit advice - VW Tiguan 2011

Hello,
I'm considering to switch my original RNS310 unit over with an Android head unit but I'm quite overwhelmed by the various systems and choices.
The reason why I consider switching is because my satnav system in the RNS310 became inaccurate a while ago as it sometimes deviates from the actual position (indicator arrow deviates approximately 30m to the West/South), leaving me with a good OEM radio / outdated media system. I also installed a Fiscon Bluetooth module a few years ago, but the sound quality is quite poor, especially when streaming music from my smartphone... and I also don't want to break the bank because the car is more or less 10 years old.
The goal of switching the unit is to use Tomtom Go (speedcam integration and live traffic updates) or Google maps and Spotify or YTMusic or DAB+ or FM radio simultaneously (by the unit itself or by a Carplay / Android Auto integration). The sound quality and phone mic must be good (actually it has to be great) and the satnav has to be accurate. A unit which is updatable is a plus (for bugfixes or compatibility with newer android versions).
As my VW Tiguan includes steering wheel buttons and front- and rear parking sensors, I would like to have a cross-integration in the head unit (similar as the RNS310 does with park pilot). I'm also afraid that changing the head unit to an android system may cause battery drainage, hence the reluctance to make the switch. When I read through this forum, I also notice that various users experiencing quite some problems with android head units which are mostly quality related.
I already looked several PX6 head units from various brands (Xtrons, Isudar, Dasiaita,...) but I can't make up my mind.
Because of these reasons, I'm asking for your advice.
Do you think that it's worth switching over to an android head unit, and which head unit do you recommend?

Question Xtrons Head unit for 2010 Lexus IS250, cant get some Steering Wheel Controls to work!

Hi everyone
I have a facelift 2010 Lexus IS250 F Sport, I've had some large success installing this XTRONS head unit for it and I am largely satisfied with it. I am however having an issue with getting Steering Wheel Controls to work with the head unit.
Lexus | Various | Android 10 | Octa Core | 4GB RAM & 64GB ROM | Integrated 4G Solution | PMA10ISLS
XTRONS PMA10ISLS is a 10.1" large screen car stereo with customized face panel and optimized CANbus Decoding for Lexus. It supports CarAutoPlay, built-in DSP, PIP mode enabled ,Dual Theme, Instant Rear Vision and so on.
xtrons.co.uk
Lexus| Various | ISO Wiring Harness | MOST
This ISO Wiring Harness is compatible with XTRONS custom fit units PSP10ISL,PMA10ISL etc. If your car is Lexus IS250/IS300/IS350 Convertible (2-door)with original navigation or fibre amplfier system,you need this cable to aid for the installation.
xtrons.co.uk
This is the unit I purchased, alongside a special wiring harness so that I could use it with my vehicle as its a facelift Navi.
With the default CANbus setting on my head unit, only Volume control seems to work and the phone call buttons and voice command buttons are mapped to functions like Radio and Hey Google but I cannot programme these on the app. With an alternative CANbus setting I get skip track functionality but I get different AC Controls and lose access to my factory amp settings.
The original wiring harness I got for the headhunt has not been used at all as I was instructed to usr the special harness, and that original harness had a CANBUS decoder. XTRONS claim that I am unable to programme the SWC due to the CANBUS needing to decode it, although I have played around with the settings and selected various different CANBUS settings.
Would anyone be able to advise me on how I can get the SWC working, would it involve plugging the CANbus decoder into the head unit? There is a 12 pin connection spare at the back but I am unsure if that would make the difference or not.

Car Build: Giant Touchscreen + Phone? or Tablet + Headunit Reloaded?

I'm restoring a classic truck and doing some fabrication for a modern DIY headunit. Should I...
A) Mount a Galaxy Tab S8+, with a big beautiful screen, on my dash and connect to it with my phone via Headunit Reloaded?
-or-
B) Mount a big beautiful AMOLED touchscreen with similar specs on my dash and connect to it directly via HDMI out from the phone?
HR on a tablet seems great but there is some added complexity of HR not being supported in the future or Google bricking it with an update. Also I'd worry about leaving a LiPo in my truck. It would be idle potentially for over a week if I don't drive it, which could drain the tablet's battery, causing it to shut down fully, then requiring long bootup time.
I could get (pretty much) the same screen from aliexpress and mount that to the dash. No battery concerns. I'd just plug in the phone as soon as got in the car and then take the phone with me, running everything directly on the phone - audio out, etc. If I went this route, though, could I configure the resolution of the external monitor? Would driving mode work?
Anyone have experience here? Which approach would you choose? Why?
Thanks!
Maybe something over in the Automotive forum threads...
Android Automotive OS
Android Automotive OS is not Android Auto. This is more than an operating system designed to implement Google features into cars. It goes beyond just adding apps and navigation. Android Automotive OS controls the hardware of the car, like the AC, lights, seat settings etc.
