Hi,
I have a JVC KW-AVX710 that I installed with a metra 70-7550 harness for a 2005 pathfinder nonbose factory unit. My problem is when I initially installed the unit in my truck it was working perfectly, after about 6 hours I went back to my truck to put in a different cd and when I turn on my truck the radio would play for about 10 seconds with a blank screen and then completely shut off. I am unable to turn the unit back on after that. There are 2 ground wires for my stock harness. 1 is the power amp ground and 1 is the regular ground. Since the JVC harness only has 1 ground wire, I simply grounded the power amp ground to the black JVC harness ground and taped up the black wire from my pathfinders harness. Could a bad ground be the problem? weird thing is the unit was working perfectly fine before that. Any help would be greatly appreciated. Thanks so much.
