I am attempting to install an aftermarket stereo (Pioneer AVH-4200NEX) with a Maestro RR steering wheel control unit.
The head unit powers on just fine when I start the car, but I am having two issues
1) I get no sound out of the speakers at all. When I press volume up or down I hear a beep coming from the head unit itself, but nothing coming out of the speakers.
2) the steering wheel controls only work sometimes. When they stop working a message shows up on the screen stating that the maestro isn't working and to check it's connections.
From the googling I've done it sounds like #1
could be an amp issue. Is there a built in amp in this trim level?
Any help someone could provide would be greatly appreciated.
