Hello again, bit of a long shot this but here goes. In my 2000 P38 there is a pioneer DVD/Sat Nav, model No:Avic-D9900V. It appears to be working but as it was fitted in Japan, all the on screen instructions are in Japanese, also the radio only works between 76 and 90Mhz. I've looked online for a manual without success, I think this model was only for the Japanese market.
If anyone has had any experience of one of these, I'd be very interested to know if it can be salvaged.
