The new radio for the 2013 Ram is completely different from the 2012 Rams
There will be 4 different radios
R1, R2, R3, & R4
The base 2013 Ram radio will be the Media Center R1; it has a four-line text display, USB input, and iPod integration, with an optional CD player.
The R2 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 next-generation UConnect comes with the next stereos. The UConnect R3 (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 R4, which costs only $500 more, and also includes HD radio. A CD player is in the lower storage bin of the center console.
(some systems have a application quite a bit like the ONSTAR in GM vehicles)
