After the transfer in mapsource, there should be a dialog box with a checkbox that says something like 'turn off GPS after transfer.' Make sure it's unchecked.
hope that helps.

Ok, I'll take a look at that and see Thks.
I've just purchase this unit and have question. When I transfer a track,waypoint etc. from the unit to the PC or the other way around the unit shuts off.Any ideas why its doing this? Also when I go to the interface- USB mass storage the only way to get it off of this is to turn unit off! Any suggestions of why it does this!
