Moving from one TT720 to another TT720
I love the many features of the TT720 so when my first one started to die I went on line and purchased a used one. The used one works great but came with an older map. Is there a way to put the more current map from my first TT720 on to the 2nd one. The parts of my first one that stopped working are the Blue Tooth and the external socket for sound so I can still get at the more current map. I see how I can transfer cars, opening screen pictures and POIs from one to the other but can't figure out how to put the newer map on the second TT720.
