the firmware in my eTrex VistaC is v2.7, I have reload the USB-drivers.
-must I use for my GPS the NT-version ? (I don't no what the difference is between the NT and the non-NT)
I read in a other forum that some old GPS-systems could not work with the NT-version. Maybe is that me problem
-is it possible that I have download a wrong version, that can't be work for my GPS.
-I have a orginal DVD with CNEURNT9. If I install that map and I unlock it with "unlock mapsource v1.3.1" is that enough to make it working ?
now it gave the same result as v14.
