Hello mates and thanks for all your useful tips. This is my situation.

I've latest version of MapSource installed with the europe 2011.32 unlocked thanks to GMAP UNLOCKER. I can see all the Europe Maps without problems.

How can I upload these maps on my 2720? I've tried MapInstall and MapSource but I'm not able to delete all the previous maps on the 2720 to upload the newst ones. The software tell me that I've just 500Mb free on the unit.

All the legitimate upgrade I've done in the past were done using the Garmin DVD with a software CNEUNT2008.exe so I imagine that I would need something like CNEUNT2011.exe to delete the old maps and install the new ones.

Is this correct? There's any other way I can put the new maps on my unit?

I've also IMGMAPSUPP.IMG unlocked that it's supposed to be the file to be replaced on the unit but I'm unable to see the 2720 as a disk so I cannot in any way upload this image on the unit.

I really don't know what to do so any help is really appreciated...
