Re: List of BMW Dealers
.gdb files are used with Garmin's MapSoruce program. Some Nuvi users may not be familiar with this program due to the fact that the Nuvi comes preloaded with all of the US maps..so is bascially ready to use out of the box wihtout the need to install anything on your 'puter. The Mapsource program (disc) and your maps should have come with your device when you purchased it. You will need to have the MapSource program installed on your computer before you can open, or work with, a .gdb file. MapSource is a free program from Garmin, but in order to use it, you have to have licensed Garmin maps installed (for example, the 2008 North America NT DVD). Anyway, once you have everything loaded on the computer, you simply open the .gdb file from within MapSource. After that, you hook up your GPS (presumably via USB cable). After the device is recognized, you choose the "Send to Device" option, select(tick) Waypoints...and 'voila. You're done.
Instead of sending every one of these dealers to your device, you could alternatively Cut/Paste selected dealers into a new .gdb file (using MapSource obviously)...then choose "Send to Device". This way....you'll only be "loading" the dealers you want.
I wish I could think of clever things to say in my signature.
