every time i use the bluetooth in my truck it always says while im on the phone bluetooth unit has been disconnected and then like 1 minute later it connects back to the z2....can any one help me with this one

Check the mounting location for your BT reciever. You will want it as close to your phone as possible while still hidden. Make sure there is not any metal sheilding it from the phone as well.

it just really started doing that.....it hasnt done it for like 3 months and i havent changed anything on the dash or the bt unit
