Android Head Unit Software

[rocket rod]

I've installed a Android head unit into my D4 and it's a great upgrade form the factory unit allowing for a big improvement in size of screen and the software that can be used. The one thing that is missing is the 4x4 info screen that showed suspension info, front wheel direction amongst a other functions.

I'm wondering if anyone with a similar head unit has found apps that do the above and any other useful app suggestions?

Unfortunately with all these Amazon purchases they change all the time and I can't find the unit I bought. I searched for Tesla style head unit for Landrover discovery 4 if that helps. I got the latest Android version (13 I think) and biggest RAM. The supplier sent me instructions via WhatsApp inc videos in Chinese so it was an entertaining experience to say the least. In the end though it's the best upgrade I've done.

If you go into settings and see if there is an option to select a canbus adapter you may get it to work, some do but most don't.

I just installed a fully android can bus integrated head unit that comes with working 4x4 screen D4 base spec aftermarket headunit upgrade by Driven Sound Vision Technology (https://www.aulro.com/afvb/l319-discovery-3-and-4-a/280431-d4-base-spec-aftermarket-headunit-upgrade-driven-sound-vision-technology-post3254807.html#post3254807)

That unit looks pretty good.

I finally found where I bought my unit from, AliExpress (not Amazon as I thought) https://www.aliexpress.com/item/1005006456272513.html?spm=a2g0o.order_list.order_l ist_main.5.11921802YGclWG#nav-description

that looks very similar, i actually extracted the 4x4 info app installer off mine for you , and also extracted it to look at the source code to see if could add more features, that im not sure of, as i think you are limited to the can signals that the decoder translates/relays to the head unit, and theres no easy way to edit that.

the app is "car info" and looking inside it, it seems it built to work for all different cars and functions (not just 4x4), but whether by detection of the installed system or just the installer has been configured, it appears as "4x4 info" in apps. it might even be the parking sensor display too, so you may have it installed already.

i also got screenshots of my head unit versions. which ill post later.

Thanks for that. I've downloaded it but not sure when I'll get to install it. Will keep you informed.

cool, let me know , no rush, i guess i could even just try installing it on my phone ... i might try that now and see what it looks like when opened

update: got error on phone "App not installed as package conflicts with an existing package" so might not be possible to test it that way, but ill look into that error some more

Is it in APK format ? Doh, should have looked the file first. I'll download it and try it tomorrow and see what happens.

RR, apk's usually go in the root like other apps.

I just had a thought, you should prob check you dont already have an app of the same name installed, incase this overwrites it, as if that is the case you need to back up that original apk first before trying the newer version just in case.

if its of use this free app lets you open and explore apk APK Editor for PC and Mac – APK Editor Studio

possibly its conflicting with a system app

Since i didn't have factory sat nav i may need to enable it in the CCF for it to work.

no, i didnt either, just to be clear get what to work ?

[loanrangie]

no, i didnt either, just to be clear get what to work ?The 4x4 info, tried to install the app but got the same message as RR.
I then looked in the installed apps and i already have the carinfo app installed so it didn't do anything, i set it up a while ago to show my car but doesn't do anything else like show which door is open etc like i see on other units.

[rocket rod]

installed the app but it said is was updating the existing one, so no change. Pity

I enabled rear sensors and now it shows a vehicle on the screen when in reverse.

do you guys know what decoder version you have ? ive attached a translated picture of mine

also in system info it says for me, what is yours

CAN version: Range-v31-240304
System version: TS18.2.2_20250820.112825_WINDOW-THEME1-V2
CarSetting Version: master-mxy.20250514_1189

Did you get or have an icon in your apps that has that grey car icon ?, as it seems the carinfo can be launched in different modes, such as 4x4 info and reverse mode , as i think they are both being done by the same app.

My head is LF-DW-TS18-QLED-202509

I haven't checked on the unit although i don't remember there being any info on it apart from the Aerpro part number, i just selected a universal canbus adapter.

[haydent]

what head unit do you have ?

[loanrangie]

what head unit do you have ?Eonon UA12.

i just selected a universal canbus adapter.

do any of your can bus work with the stereo ? do the steering controls work ?

Breakthrough ! I just had a deeper look into the apps installed, and i found it was actually a different one that does the 4x4 info screen, same icon, but called 'car setting' i was able to launch it from an app explorer to confirm its the right one. And now when i explore the apk it has mention of 4x4 info, where the other one did not, which got me suspicious.

ive added it to the original download page https://www.aulro.com/afvb/vbdownloads.php?do=download&downloadid=32

Yes al buttons work and extra functions that i have programmed to them.

apart from buttons, do you have other can dialog ? (steering buttons dont use can, though they can be relayed by the can decoder)
