I have exactly the sam problem...
when I start up the pc and then starte CentraFuse, and click NAV, it is like the program does not start op a connection to the gps, If I close the programe, start MS Mappoint, connect to the gps, close Mapppoint, start CF enter NAV, then the gps is active.
Why does the CF not start the conn. to my gps?
When CF shows the Speed in Km/h the speed is wrong. Allthough I drive 80km/h its only showing aound 18km/h, I don't know if the problem only is in meteric?
These are all known issues and have been talked about numerous times... I'm working on them and some have already been fixed... search the forums...
