![]() Step 4: Updating the map package in the car. Just click ok, you may need to restart your car one time to click out of the pop up. Let it load and it will still say cannot unlock maps. NOTE: After you flash this it takes a long time to load. Select garmin recovery update and plug in the usb drive with CTP13 on it. Turn on the car and hold temp up + temp down + front defrost, after a few seconds dealer mode will pop up. ![]() The one I found was not for a dodge journey, however it still worked. Take a second USB drive with the gupdate.gcd from CTP13. Step 3: Downgrade radio navigation to CTP13! This is very important as newer versions have secuirty that prevents loading of maps without dealer codes. A command window will flash by, so fast you may miss it if you blink. It will only take a couple of seconds to unlock both files. (See links at bottom for garmin image tools) To unlock the two files, simply drag-and-drop them one at a time onto the "gimgunlock.exe" file using your file explorer. Step 2: The gmapprom.img and gmap3d.img files should be manually unlocked before they go into the car using gimgunlock.exe. | 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.
