@Neil I will just ignore you and all your shot in the dark answers which does not help anyone.

@trav7414 - You asked if u should delete all 4 .img files.

The answer to that depends on what map you want in your Garmin. The download from installous comes with a USA map.

The four .img files are:

- gmapbmap.img - this is the world base map. You can keep this map because its a summary of the whole world and its size is small.
- gmaptz.img - this is the time setting. You can keep this because it is small in size and u may need it when u go to different countries.
- gmapprom.img - the map downloaded from installous is locked. You can delete this and download an UNLOCKED map somewhere (checkout the latest map in this forum)
- gmap3d.img - this is the 3D buildings in USA. U can delete this and download a new 3D which comes with yr new map.

If u are looking for USA map, u can download from here:

download the CN North America NT 2012.40 UNLOCKED IMG - NOT the MAPSOURCE one.

You should also re-download the JCV file and replace the JCV file in the /var/mobile/Applications/???numbers???/garmin-nav.app/storage-usa/.System/JCV folder. I used the D3060050A.JCV file.

Hope this helps. Because if it does help then i would have helped 2 people more than @Neil.
