if you had the 8.4" radio, either RA3 or RA4, you would change the setting using the radio in the MENU
with the 3" RA1 or 5" RA2 radio, you will need to either read your owners manual or ask someone
The base 2013 Ram radio will be the Media Center RA1; it has a four-line text display, USB input, and iPod integration, with an optional CD player
it does NOT have bluetooth
The RA2 adds a five-inch touch-screen, speed-controlled volume, satellite radio, phone and voice control, EVIC personalization, and GPS receiver; a rearview camera and remote CD player are optional.
The UConnect RA3 (8.4 inch touch-screen) adds UConnect Access, including crash notification, 911 or roadside assistance calls, monthly vehicle health reports, voice texting, WiFi hotspots (pay per use), dead-reckoning with gyro, and optional rear-seat Blu-Ray DVD player; buyers can pay $595 to upgrade it with navigation. But those who want navigation should get the RA4, which costs only $500 more, and also includes HD radio. A optional
CD player is in the lower storage bin of the center console.
The Uconnect Media Center RA4 adds HD Radio, SiriusXM Travel Link, and SiriusXM Traffic and a remote USB port in the media console to the RA3 capabilities.
