Jrobles376 - be certain what you are asking for.
The Metra is simply a plastic shell. Any standard DIN or Double-DIN radio will work with it.
Now - BT, NAV, and DVD are fairly standard for Double-DIN HU. I would recommend looking at Pioneer, Kenwood, JVC, or Alpine - maybe Clarion also.
Rear camera is also pretty standard, but you would have to install the camera on your car and run the wiring back to the head unit rear video input.
Internet browser will be an issue - some of the Pioneers with AppLink and some of the JVC's with Android support can probably do that using your smartphone. Otherwise, you are going to need a mobile hotspot and a computer interface - in that case, I recommend copying Mr. Peaches setup above.
