Once again this problem is back. Last time I redid all the wiring and just thought it was wiring. Doesn't seem to be the case. Nav and all functions work fine, it's just the sound. When starting up I can press a button and instead of the "beep" you get nothing, then when it starts up and you press a button, the load static pop. Any ideas? I've removed all the extras like the bluetooth, XM, iPod to remove them from the equation. I'm at a loss as this comes and goes.
