So here is my 2006 RT and started off with this bad boy lol   I was not impressed  and looked for a REC Nav. Found it!  And also the Nav Bezel for $130 at the dealership ( 1CB331ZB-AA NAV Bezel )  GPS Antenna ( 56038630-AA )  Cant forget the TVandNav2Go  All Done~  I never got the TVandNav2Go to work because it was wired wrong and it just didnt work with my REC. So I got fed up with everything and sold it all haha. The New Fun Begins!   Sundown Audio SAE 1200 RMS and thats rated at 13.1v  2 12 inch fully loaded SSD's from Fi Car Audio.
