Detail maps only show up on my PC when I have the GPS unit plugged in. I always download the maps to the PC - That seemed to go fine last week but now this.
What am I missing?
Long for the old map program it was so much better.
Well the old map program, by which I assume you mean MapSource, can't read maps off your device so would be useless now if there was an issue downloading the maps to your PC.
If something has gone wrong in downloading the maps just download them again.
