All the Radios in 2009 + Ram 1500s are the same size.
You no longer have to swap out the bezel when you upgrade from the standard radios to the navi radios.
Both types of climate controls will fit in the bezel. You will see that the bezel has a standard oval-ish cutout that the regular one and the auto controls will up. The only difference in the bezels is the colour.
Oh yeah...nice review of the '11 garmin navi!
The '11 Journey, 300, Charger and maybe some more have new radios that look like this:
They can't be swapped in as they are a different size and probably a different connector and possibly bus.
