SOLVED. When I matched the camera resolution to the screen size .... 800 x 480, it worked. Screen is no longer black when in reverse.
After correcting the black backup camera display, I'm now stuck in the black screen of death as soon as I engage AA.
Suggestion: Adding the page number on each page of the manual would be nice.
How I fixed my backup camera: I changed the video setting in OAP 3.3.2b from 720 to 480. The camera now works under all testing circumstances. But when I connect my phone (and Android Auto) via USB cable, the screen goes black.
So, following your instructions,
1. My equipment meets system requirements. I have a Pi 3B+ with a HifiBerry Amp2 HAT, external Panda Bluetooth dongle, 7 inch Raspberry Touchscreen, HDMI cabled PI Fisheye camera on a GPIO relay switch. My phone is a Samsung Galaxy S7 edge.
2. Are all permissions granted in Android Auto on my phone? I have no idea. I installed it from Google Play Store and no permissions were requested. Pressing the settings button in AA lists no permissions per se so just to be sure, I confirmed that all applicable settings options are on.
3. Developer Options settings, pg 19.: Page 19 says that the developer settings are to be found in the AA software. I found no such settings there. Might you be referring instead to OAP? If so, where could I find them? They are not listed in the manual's table of contents.
Please advise .. I'd love to get out of this black screen.
