| gmapdem.img (Digital Elevation Model map / terrain shading) | gmapbmap.img (Basemap / non-detailed maps) | gmapprom.img (North America Detailed maps) | gmap3d.img (3d Buildings North America)
All files and sub folders go in that folder. When you first open the usb drive you should only see one folder, Garmin NOTHING ELSE. When you are finished, the folder/file structure on the USB stick should look like this for 2017.20 map files: I will not post a direct link here to avoid any rules about piracy, I am sure with a little googlefu you can find the files if you search for ( gps power "gmapprom.img - Original Locked" ) or even torrents. HOWEVER, you can get almost all of them from the net. STEP 1: First you need the files, most people pull these from a nuvi or the update cd they purchased. So in an effort to actually help the community since dodge has F***ed us i will post my results / steps so far. To further compound the issue its not like you can install an aftermarket radio with nav as this radio controls the environmental / ac / etc. Course it costs 100.00 to replace the radio under extended warranty (1500-2000 without) and people on this forum will charge you 100.00 to help you, Plus they want your personal information. Many pages of posts and no guide / fix posted.

Execute the command Maps Manage products maps, and see that indeed the state of map is “locked” but we’re interested is the installation location which we’ll take note: is needed.We’ll get a warning that there’re blocked maps. If not listed we need to know where is, for this run BaseCamp.Lets go to ‘MapSource’ tab, will appear us the base map and we have luck the locked map, then would select it and go to step 5.Warning! there’re two executables, one for 32bits and other for 64bits. I will assume already you’ve installed the locked maps or go after some, I must warn you don’t download installers from anywhere because can place in the same installation «another things», do it in a site or uploader trusted. At the beginning I unlocked some maps in MapSource by pure filly, now the issue has fallen back into my hands and I decided to create this post.
