What is the benefit of using BaseCamp if have MapSource except that there is a file folder so can see the GPSr in BC?
BaseCamp is more stable than MapSource in Win7. It still crashes, but only about 1/3 as often as MapSource.
This no longer is true. MapSource 6.16.0.2 Beta is much more stable than BaseCamp in Win7. 6.16.0.2 hasn't crashed on me yet.
what is the firmware version you're seeing and what is the basemap (name and version as reported by BC) that is on your 400t?
