Hey all,

Hoping someone can provide some guidance.

The OEM touch screen formed bubbles under it and was registering touch inputs randomly - common issue. I replaced it with a generic android tablet head unit, similar to the idoing unit. I purchased it from AliExpress, unfortunately the seller has become unresponsive.

The seller provided a suitable canbus adapter and custom harness cables which should supposedly be plug and play. It was not.

I can't get the reverse camera to work. It will switch to the camera feed when I shift into reverse, but it's just a black screen. There are a number of resolution and format settings to switch between, sadly none of them make a difference.

Also the steering wheel controls won't map correctly. Some buttons are duplicates. For example: volume up and back arrow register as the same button. I can't map individual functions to each of these buttons. Same applies to the answer and hang up button. I've switched to various models and steering wheel types with no luck.

I think getting the reverse camera working is my higher priority. Any suggestions, or is this a job for an auto sparky? Thanks.
