Factory 2011 nav system

Best prices I have found have been at www.sonicelectronics.com their people were very helpful during the purchase of my Kenwood DNX 9160. They have the sync retention cable as welll as the Steering wheel integration harness.

I did a nav swap on my 450. It's a good bit more involved than just changing a head unit and plugging the harness into the back. I needed a audiophile amp (mounted where the old sirius tuner did) needed an gps antenna splinter wire. Needed to cut and solder in 8 locations. Had to find a factory sync harness to scavenge connectors from. Needed a audiophile to head unit harness. When I was done I still needed a different steering wheel switch to operate the factory nav. Took a days work and 3k worth of ***** from eBay and scrap yards and fomoco. But was exactly like factory.
