Will MacGPS Pro work with the eTrex receivers which only have a USB connection?
MacGPS Pro will work with the etrex Vista and Legend C, Cx and HCx receivers when connected to a USB port with the Garmin-supplied cable. MacGPS Pro will NOT work with eTrex Venture C, Cx and HCx receivers or the eTrex H receiver, so purchase an eTrex Vista or an eTrex Legend model instead if you want to use MacGPS Pro.
