Thread: MapSource or BaseCamp?

When Garmin introduced BaseCamp it was only for maps with DEM layers. Now you can view almost all maps except marine charts. The best feature is that you can view IMG-maps (like gmapsupp.img) directly with BaseCamp. It works if the maps resides on a attached Garmin GPS unit in storage mode or with maps on USB memory readers. Files created with MapSource needs modification to set MS flag = 0 which can be done by [Only registered and activated users can see links. ].

I prefer to use MapSource with genuine MapSource maps and possibly BaseCamp to read IMG maps or MapSource maps with DEM layers in 3D simulation.
Use [Only registered and activated users can see links. ] for marine charts like BlueChart g2 Vision.


About "unauthorized" maps

Spoiler: CLICK

In both cases you will need the patched variants of [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ] if the MapID >= 2200. That's to overcome the GMA protection with digital signature files. GMA files are Garmin's new way to protect their maps from unauthorized copying. The GMA digital signature is unique for a specific unit and only issued to the original licensed customer.
If you transfer a map with MapID >= 2200 to your new 62ST you must either have the genuine legal license or remove the locking completely with one of the unlockers [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ].

The 25-char unlock code is not fully functional (it's only unlocked but not authorized) with newer firmware if MapID >= 2200 and the genuine GMA file is missing.
