When you start a TT with the old map deleted and a new map added some devices only check for the location of the map as defined inside the CurrentMap.dat - which won't work if the map folder is different and/or the map is different in name. This in return can cause the device to hang and become non-responsive, not even reset or Clear Flash will help.
Similar thing can happen if your old map was for example a Europe map with the last use in Europe. If you replace the EU map with a US map (and have not got a proper sat fix before) the TT can't position you on the new map and can freeze too.
IMHO the safest way to avoid problems when installing a new map is to delete the CurrentMap.dat and CurrentLocation.dat in the root after the new map is installed and activated and before you start the TT with the new map.
Might also help once you got the problem already.
