Guys - I bought my R/T with the RAQ 6CD/MP3/WMA etc... It is standard with the Sound Group II optional package. This also comes with a 322 watt Amp, 6 speakers and a Sub-Woofer. So to answer the amp question, I'd say the upgraded RAQ system has an RCA out for the amp... You'd have to get specs for it to determine that for sure. Anyway this R/T had all options but NAV and Rear Seat Video. I wanted the NAV so I bought it separately at the dealer. This NAV system rocks!! It has all the options as the RAQ (6CD/MP3 etc) plus NAV and a large flat panel display 5.8" with lots of info. Anyway, I am now the proud owner of the RAQ radio and the Silver Bezel to match. I kept both of them, as I paid for them and made the dealer return them to me. They are exactly 2 weeks old, and will fit perfectly in your charger. You may be able to get some from a Magnum or elsewhere, but the Dealer price for this RAQ stereo and bezel is around 500.00. I am considering selling them for 300, but I may hold them as they are original parts to my R/T Charger.
So to add to this, the dealer replaced my Silver Bezel with a black one, since the NAV radio is much larger than the standard and RAQ models. I now am in the market for a Silver Center Bezel that will fit the R/T NAV system. Right now Dodge states its only available in cars out of the factory with NAV.
Thanks!
