Fixed the Arduino power problem.. I have ACC and 12v reversed.. it must have be wired correct, then I changed it and made it wrong
I don’t have the audio for the HD tuner hooked up at the moment, it is muted I believe and I cannot figure out how to up mute it. It was fine earlier today
There is also what sounds like low frequency noise ( sounds like grinding) through the speakers.. once I disconnect the HDTuner it goes away. I have to wonder if it is the added wire I put in the tuner to help with grounding ( for testing)
my Headunit has a radio so i can use that for now..
