As the Uconnect systems fitted to Dodge Chargers use Garmin navigation, Garmin files (*.img files) will work in it. I'm not familiar with that system, but if it uses a media card for maps, you will probably find that the unlocked image may work saved as gmapsupp.img in the card's root folder named Garmin. If you need further help loading it etc, best to ask in [Only registered and activated users can see links. ]. Be sure to back up any data before replacing the current map.
