In dash replacement stereo for 2005 A4
 

I would like to replace my stereo with a aftermarket unit that integrates GPS Navigation system and a rear view camera display on the display of the radio/Cd; Is there such a system available for a 2005 A4 for under $500?

I do know that the Pioneer AVIC-Z140BH has the rear view camera input but it costs approximately $700 on Amazon just for the radio.

Take a look at the Pioneer AVH-X3500BHS on Cruthfield.com. There are also two more step up models that may have nav.

$300 for base headunit that will accept video from rear view camera as well as add on nav. Nav unit is $400 but this unit also connects to Android to share apps.

I will be installing over the weekend and let you know how the Android app connection is as I plan to use that for my nav instead of an installed module.
