when i zoom in and start panning sometimes the map will disappear, to get it back i have to shut down an restart. the maps are ibycus usa. i do have the latest updates installed. also it did this on the earlier updates also. this dosen't happen until i pan for a while an the the map is gone. thanks jim
i dig ginsang, in the summer months while it is growing ( before it is legal to dig ) i do a lot of woods hikeing and when i find some nice sang i mark it on my gps, made enough last year to pay for my garmin 60csx.
