May not be news to everyone, but there are pretty handy Apps for both RAM and Dodge vehicles (vehicle specific). I think they are limited to 2011+ support though.
Just search RAM or DODGE in the App store as needed or click links below. A lot of the tech questions can probably be answered within the APPS, especially radio.NAV/maintenance stuff. Enjoy.
