[Android Head-Units] tonytigerrex:
Hi guys, after googling through this forum and several others for days, Youtube videos, etc, etc I reached a point I am at a dead end guess I need some help, some weeks ago I bought this unit from Aliexpress Seller Skyshadow (yes, it seems to be a recurring problematic seller from what I gathered reading XDA posts).

Seller does not provide any support other than a PDF with the GUI features and that is it... also my Android Version that came installed was Android 11 not 12 but I digress...

I made almost everything work except making calls and running carplay, found the 3368 factory code from somewhere and managed to get into the factory settings, in some other post somebody says these head units are the same as Navifly ones and some other said they are Medeke / Mekede (sp?) but the settings and options are named totally different and I have not been able to make the reverse camera display something else besides "no signal". Already checked the camera connected at the CVBS IN jack and when going to the aux app it shows great video resolution, the canbus pink reverse wire is working properly and it triggers the reverse display but no signal is shown when connected to CAM IN or CAMERA IN jacks.

Currently the unit detects both SIMS properly and even when they are active lines, it says when trying to dial: "cannot place call in current state", I could live without 4G connectivity, but the reverse CAM is a must.

I already disconnected the pink reverse wire, put the car in reverse so the camera got voltage and it showed me a perfect picture in the AUX app, if I connect it to the yellow CAM In or CAMERA IN, then no picture at all. I cannot find a setting to enable camera for these inputs.

This is the CVBS-AHD 1280x720P camera that I am using and its working properly on any input except on reverse:

I already connected another camera and same story, cut the white wire to convert the camera from CVBS to AHD and no luck... I already tried another cable, gender changers, other cameras, etc, etc, etc and the head UNIT properly displays the image on CVBS IN 1 and CVBS IN 2 jacks, but connect it to CAM IN or CAMERA IN and... "no signal", I already tried to find all the possible menus, settings, restarted the unit, etc and absolutely no luck.

I am enclosing some pictures in this post to help you identify if I am doing something wrong of if its there a workaround I can do to make reverse work with CVBS IN 1 or 2 instead of the CAM IN or CAMERA IN jacks?

Thank you very much for any insight you can provide me.

Here is working properly showing video in AUX APP CVBS IN 1:

the CVBS IN jacks and the canbus decoder box with the pink wire connected that properly triggers reverse:

The message I get when going into reverse with the camera connected to the CAM IN or CAMERA-IN jacks:
