Ok, so the bluetooth on the z120bt is about as crappy as can be when it comes to people hearing you talk. So I figured I would shut that off, and use the bluetooth on the vehicle itself. Talked to my wife and she can hear me fine, only problem with this now is. Instead of the stereo muting like it should normally do, it would reboot itself. When an incoming/outgoing phone call is made, the whole radio would shut off instead of just muting. Anyone else having this problem, and what type of fix should I be looking at?
