I have a XRS9700 and used it in a 2004 BMW 325 with no problems at all.
One month ago, I moved the unit to a 2007 BMW 328. The intellimute feature never really worked well in this car at all, but all other functions/warnings were ok. One day the compass started showing North and South only.
Despite numerous attempts to recalibrate the compass including returning to default factory settings, it never returned to normal. Even in another vehicle, the compass is still N/S only.
Is the compass totally screwed or is there a way to reset the unit??
