I have garmin mobile xt installed on my 8GB SD card which sits on my sd slot ....it works great!!! sprint touch pro.... mine is one of those versions that is a no no to discuss...as far as transferring from their SD card I am not sure but I dont think so...tomtom navigator is the same way.....I think it would be quite a pain in the @^# to switch it out when you want to use it.....it is very handy to have sitting there and ready at the touch
