Re: Want to Replace RES radio with 430N RBZ, does anyone have one?
Two other threads in the past 7 days on this exact subject... popular topic. The E package did not come w/ Uconnect by default, it must have been an additional option package.
2011 should be plug and play into your 2012 and will work with the factory uconnect and sirius options. All you will need is the head unit. I used part number 5064685AI successfully and this model does support Uconnect/SDARS and Rear Camera. Any revision of 5064685A should work, I have no experience with other part numbers. For a 2012 I do understand you would need the security code but there is otherwise no differences.
I have a source for RBZ radios, you can PM me for a price. I also am having the dealer install the backup camera kit, for $150 in labor it's not worth ripping the whole interior apart, and this way it gets covered by your factory warranty. I understand that the camera will need to be coded to work, so even if you DIY, your paying the dealer for programming.
