I have excatly the same problem on my new 7 inch android 8.0 Pumpkin autoradio with parking camera in my VW Passat.
If I hit brake - i got triangle or black screen.
Put to the reverse, without braking. Turn on left or right or all 4 (emergency) turn signals. If you see the picture change, or blinking or lines in picture, you have problem with GROUND power taken from reverse lights to power your camera.
I do not use the resistor.
My problem was solved simply to connect another wire for ground (negative) directly to car frame, chasis in the trunk - to camera power cable (negative wire).
Until then - my reverse camera works perfect!

Today I hooked the 10K resistor back up to to system and results are the same as without it hooked up.

I checked voltages and tried to upload the video but get an error "Invalid file extension: RCA Cable voltage.mp4"
readings are taken at radio end of RCA cable red power wire hooked up to reverse light power wire at rear of car (white with green stripe). Camera ground is at ground terminal of battery in trunk. Voltages are 0 volts when in park and no brakes. When brakes are applied I get .3 volts. When reverse is selected I get 9.5 volts. This is with engine not running, same conditions as when I would get error.

1. disconnect the 10K resistance .
2. you connect the red wire on the rca cable to another 12V positive pole when you put the car in reverse .You can show me some pictures about this point .If you have a mutimeter , you can check whether this wire get any power and how much when you put the car in any gear except for the reverse .
More query , could you mind showing an video ? It will be exactly helpful to find the cause .

I purchased and installed in my 2006 Dodge Charger SE, a Pumpkin 10.1 Inch Android 7.1.2 Stereo off Amazon (order 111-7299203-8131401) along with the Pumpkin License plate backup camera (Amazon Order 111-3095051-1717056). It was installed with the Metra dash kit and harness. Stereo install looks and works great, no issues with that installation. Hooked up illumination wire to parking lights so screen dims with light on perfect. Then installed reverse cam red wire at camera (both red to cam and red wire on RCA cable) to white/green stripe wire (taillight reverse light,12v when in reverse only). Installed radio side RCA red wire to Reverse -In wire at radio harness. Reverse camera works perfect, when in reverse camera comes on and goes off in any other gear. I have an issue with the screen and get a Warning Triangle error when I am in any gear except reverse and apply the brakes. I looked over the forum and found similar issues where a 10K ohm resister is added to ground at radio to reverse-in wire. I also tried this but it was no help. Unplug RCA cable at radio and cut red wire and issue goes away. Is there an new patch or any other help you can provide?
Thanks,
Jay
