Thread: About Garmin maps Additions files (gmap3d-JCV-gmaptz-ASR-G2S)

Catymag, I know that you've asked to avoid Thank You posts - but this being the clearest tutorial on the subject ever, I could not resist... ThankYou!

Great info!

Got me a bit confused though, I have a Nuvi 3790T with built in North America maps, and I plan to install the 2011 Europe and 2011 Middle East maps, but I see some people around the forum saying that maps have 2 versions, a MapSource version and a regular version, according to some posts, the regular version will lose the map preview and some search/index capabilities, how true is this?

Since I'll be using the JCV and 3D files, does the latest MapSource support Lane Assist and Junction View files? Or am I going to have to move those manually to the device?

One last thing, after looking through my device, the following files "gmapbmap, gmapdem, gmaptz, gmapprom, gmap3d, gmap3d.sum, gmapbmap.sum, gmapdem.sum, gmaptz.sum, gmapprom.sum" are located in a hidden folder "F:\.System". I assume that in the case I use Map Source to install the maps, it will take care of putting them in the right location, but what if I had to move the maps manually, should I put them in the same hidden folder "F:\.System" or should I just go with the Garmin folder? Please let me know if I'll be losing the Map Preview and Searching if I move an unlocked map manually.

Thanks a lot in advance, really appreciate the help I'm getting.
