There is a post on here and I know for sure on the RAM forum about swapping out radios. Unfortunately, there is no download for it...it much be a full radio upgrade. The parts are:
RADIO: 68331631AH (UAQ w/Nav) or 68331635AH (UAS w/o Nav)
MEDIA HUB: 68328704AC (RAM) $100 OEM
MEDIA HUB CONVERSION HARNESS (see RAM Forum) $35
Depending on how your truck is already equipped, you may need the AlfaOBD software to turn on or change a few settings.
