Before you start, you will require - Installous, iFile (trial version is ok).
Step 1 : Download and install "Garmin U.S.A. 2.0" from Installous (not Garmin StreetPilot 6.5.5).
Step 2 : Use iFile to look for the folder where it is installed and go to the ".system" folder (dotSystem not System). It should be in /var/mobile/Applications/???numbers???/garmin-nav.app/storage-usa/.System
Step 3 : Delete the .img files in the .System folder (you will have to download new map files)
Step 4 : Use iFile to modify the /etc/hosts file (putting the 127.0.0.1 triplew.garmin.com and gold.garmin.com) & Save. Make sure you check the ownership.
Step 5 : Restart iPhone and open the Garmin program.
Note 1. If you see "Activation of maps require internet connection" it means you didnt delete the .img file in the .System folder.
Note 2. If you see "Authentication failure, must buy original apps from appstore" it means you didnt modify the /etc/hosts file properly.
Step 6 : Use a computer to download a map for your country. Search for the latest map.
Note 3. There are 2 types of maps. Unlocked or locked. Read more on how to unlock a map using a keygen.
Step 7 : Insert the map in the /var/mobile/Applications/???numbers???/garmin-nav.app/storage-usa/.System folder. The map should be named gmapprom.img (some maps you download may be named gmapsupp.img just rename it)
Note 4. If the map is a locked map u have to create a gmapprom.unl file to unlock the map. Put it in the same .System folder.
Step 8 : Finally, make sure the gmapprom.img file has the correct ownership – i.e. Owner mobile, Group mobile, User read write execute, Group read execute, World read execute.
Now your Garmin USA should work on yr iPhone.
(I just got mine working this morning – so if there are any errors on my instructions please correct me)
