Garmin på iPhone

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 www.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.
