I literally just found this from Googling. I've been looking for a good solution to make use of my phone by mirroring it onto a double din dash system and controlling my phone from it, and also installing a backup camera as well. I don't know if this radio allows for the back up camera, I think it does according to the feature list on Amazon.
So I found this: Amazon.com: Pioneer SPH-DA100 AppRadio Car Stereo with iPhone 4 App Control and 7.0" Capacitive Touch: Electronics
Through user reviews, I found this app for Android compatibility with the above device: ARLiberator.

In regards to the previous link, apparently there will be a double din dash system called Devium, where you can slip in your phone and it becomes part of your car stereo, instantly. The website supposedly has been taking pre-orders for maybe the last year, hence the initial post of the thread I posted in caraudioforum.com is almost a year old. Apparently the product still isn't out. However, for me, my MAXX's screen isn't big enough to operate while driving (err, while at a stoplight/stop sigh). Might be useful (for me) if it projects your screen onto a 7" screen.
Fellow DROID RAZR MAXX users of this forum, have any of you tried this? If so, comments on functionality?
EDIT: You have to be ROOTED to use ARLiberator. I don't know if there is a way to root in JellyBean for the MAXX yet, is there? I downloaded the early version of JellyBean, I was never rooted.
