Rodrigaj - I prefer the DVD since I can use the maps in MapSource. This is the way I've always done it, since my original unit did not use SD cards. This is just my way of doing it, have a preloaded microSD might work better for others. As far a converting tracks to routes, Mapsource does not seem to have that function, but you should be able to load the track into the 60CSx and have the unit convert it on the track screen (TracBack).
