Factory and Aftermarket radio wont turn on
I have a Pioneer AVH-3200bt in my 07 coupe and the radio wont turn on until its been running for 20 mins or so. Sometimes it will turn on immediately when acc is on but when you turn the key more to actually start the car, it wont come back on. This issue started a couple of months ago and got progressively worse. I've checked all my connections with my wiring harness and everything is soldered tight so I think it might be an ignition switch ground. This happens with both the factory and aftermarket radio so I think the issue is not with the stereos themselves. Any help is greatly appreciated.
