stock D1 & Dinc. BT keeps shutting off at random and most times comes back on, but other times have to turn off BT or reboot. Maps don't continue updating location when BT is being used many times. Some type of static comes on at times and usually in same location. Map freezes or has partial blank/grid screen, unable to locate many times when using BT. Doesn't seem to make a difference what type of BT I'm using-JAWBONE or CAR system. Do you have and idea what's going on with these seemingly related symptoms?
