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.

Any help?
