I have 2 StreetPilot 2720. Currently I have CNNANT 2012.40 installed. I have attempted to install CNNANT 2013.40 using gmapprom.img. On each attempt (with each StreetPilot) after completing about 80% of the install I get a data transfer error and the install aborts. . . . . . . I then attempted to install 2013.30 version with the same data transfer error results .
I then reinstall 2012.40 with no problems.
Is the 2013 version larger (?) different (?) not suitable for the SP2720 (?)
Any suggestions will be welcome.
