I have a new in the box never used plug-n-play Garmin GVN 53 that mounts in the glove box and integrates to output the map display on a Volvo NAV screen. All you need to do is buy a used Volvo screen and grille on eBay and install in place of the grille on your dash...takes 10 minutes.

The Garmin is controlled with a remote just as the OEM system. It gives voice commands and has multiple choices for visual displays on the screen. Also has ability to look-up restaurants, hotels, gas stations, etc.

I had the same system in my S60 and bought this new one when I thought I was selling my car and getting a different Volvo; I decided to keep the one I have so now I need to sell the Garmin system. I am asking $150 but am open to offers.
