Hi again, it worked! Thanks a lot.
About to get IPhone 5, read somewhere we are not able to change the maps in app under ios6.
Anyone using ios6 and sucessfully modified the iphone files to use StreetPilot on board?
Still not working for me.
I have an un-jailbroken iPod Touch with iOS6 and want to install custom maps.
I downloaded the iExplorer and able to browse to the desired directory, but it won't let me delete any files! I can copy my own gmapsupp.img as long as I do not replace any existing files, but when running the application, the map does not appear as loaded.
I have been trying for quite a while using different programs like iFunBox but no luck.
My iphone is JailBreak 5.1.1... I buy in AppStore U$5,99 the Garmin-China... Installed, than download the minimum sized map (50mb) south china... I use iFunBox to open de .System folder... Delete ALL .img. I copy mine "gmapprom.img", add the permissions.. And the map not working. What i can do?
Make sure that you're using an unlocked map. If yes, there are some Garmin apps that have an additional protection of not allowing unlocked maps to be used. Some allow the workaround of renaming the map as gmap3d.img instead of gmapprom.img and it still works as a routable map. Some of the newer garmin apps do not allow that either. Then you could try replacing the executable with this one from the US app [Only registered and activated users can see links. ] Unzip and put into the garmin-nav.app folder.
Tip for those who cannot edit the plist-files. Copy them using iFunbox to your PC. Edit them on the PC (using notepad or plist editor) and copy them back to the iPhone. I never worried about permissions or whatsoever and the modifications work fine. Only thing is to force the Garmin to close (doubleclick home buton and keep icon pushed until x appears to close). After restarting the App the modifications are effective.
I have the Garmin USA v2.2 ipa without the maps and when i open the app it gives me Authentication Error. How do i resolve this and can anyone guide me on how to get the USA map files for my iPhone and what location do i place it.
