Thread: How to upgrade Garmin map on DNX7200

I will delete these map bases and will put the new file. I'll have to rename the Bmap_alt file. If I put up with the name Gmapbmap the GPS does not recognize it.

these maps you must RENAME them as:
Bmap_amr.img --> Bmap_amr.img_old
Bmap_atl.img --> Bmap_atl.img_old
Bmap_amr.img --> Bmap_amr.img_old
so your Kenwood will NOT recognize these img files and not load them (you could delete them, but I prefer to rename, not lose them...)

Then, you put Gmabmap that ORAK gave you! Only that!

After that, you must copy CityNavigator to SD card (if you have last firmware to Kenwood it can recognize 4G card, so you can put Full Europe in SD card) Don't forget to make a folder "Garmin" to SD card and there you put Citynavigator with name gmapsupp.img

JCV files not recognized from Kenwood 7200 not other files that new CityNavigator use... (unless something new came, and 7200 can recognize JCV files....)

You must use ONLY CityNavigator NT (not NTU)

Don't put other maps in the internal memory of your Kenwood, but only basemaps!

CityNavigator you must have only at SD
