It's actually a simple question. My 2000 540iA came with factory Nav...the MKII/4:3 monitor and I recently upgraded the components to MKIII/16:9. Everything seems to be working but I'm having an issue with the map. When I enter a destination and wait for the generating map prompt, no map or arrival time appears but if I go to "Dest Input Map", it pops right up. Do I need a new wiring harness to make this feature work properly or is there another problem? Thanks...
