There is too much resistance in the wires of a 15' extension cable for the A129 PRO to be reliable, I think even 10' might be too long.
The most visible symptom is the LCD display having unstable brightness. Other symptoms are having the camera randomly restart, or lock up. This might be the reason my A119 v2 was behaving badly too.
I wired my car with a 10' cable to the front location, and a 15' extension to the rear location (needed 12', but that length does not exist). I was having trouble with my rear location, so I swapped the front camera with the rear, the problem stayed with the rear.
I measured the voltage, with no load, I was getting 5.15V, but when I plugged the camera in, the voltage would fluctuate, sometimes dropping as low as 4.35V.
I have ordered some USB connectors, and when they arrive, I will wire just the power with lamp cord, that should be low enough resistance to make this work.
