Hi, I've just got the classic problem of the bluetooth module becoming disconnected from the head unit (Blaupunkt Sat Nav model), and just muting when Phone is selected on the HU. It happened whilst performing a battery swap out. I believe the first step to fix this is to reset the Bluetooth module, (often made by nokia), but before I start ripping trim out, I wonder if someone can let me know where to find it, and the best way to access it. Also if there's an easier way to reset it than unplugging, waiting 20mins and replugging, I'm all ears!! Many thanks James
