Hey guys, I had a problem where when starting the car, randomly the unit would not turn on and the only way to get it to come back on was to pull the batter cable to reset the C2R-VW2 (VW specific)or other vehicles that use pac controllers. Also, when I would start the car after listening to the radio with the ignition on, the radio would turn off and back on.
Both problems were fixed with a Metra E5000 SPDT Relay SPDT Relay w/Socket. If anyone else has this problem and needs more detail, contact me.
