NAV upgrade...no mapping. Why??

    OK...semi-successful upgrade from MKII/4:3 to MKIII/16:9. All OBC functions are operational and it looks sweet BUT I'm having an issue with the map. :(

    When entering a destination, the system prompt "generating map" comes up but no map or arrival time appears (just a black screen with some genral info). If I go to "Route map", a yellow screen appears with my destination text but no map. If I go to "Dest. map input", a few seconds later, a map appears showing my destination pinpointed (still no arrival time though). :confused:

    What could the problem be? I noticed that the small pin (NAV wire) was on the back of the MKIII but not on the back of the MKII (it goes to the big metal box mounted under the driver's tail light). I've tried operations with the wire attached to both places with the same results. My guess is that I have the older harness, which is incompatible with the MKIII. Any ideas from someone who actually is familiar with these systems?

    Thanks...
