Those familiar only with older nuvis which can flash gupdate.gcd from the Garmin folder may find that Montana 'disappearing GCD file' strange also. Horses for courses i guess .

Naturally, if you simply use 'copy & paste' for the new file or load it by dragging it onto WebUpdater the new file will overwrite the old gupdate.gcd if it's present. Remove an old file prior to flashing in preboot or via sd or the old file can be reflashed.

For those who don't like messing around with their units in this way, of course the fw an be upgraded in a 'hands-off-way' quite simply from the Garmin servers via WebUpdater or GarminExpress or directly thru mygarmin.com>MyDashboard:
