Owners of new Series Garmin devices should be very careful when using sets, first run must always be from SD/MicroSD Card NOT FROM INTERNAL MEMORY. Avoid using internal memory & big sets, 3in1 and higher, there's no reason to use them anyway you can have all the maps you need in the "Map" folder. These files are very useful in PNA, PDA, Symbian & older Garmin devices where you can increase the number of maps you can have in your memory card.[/color]
