I am looking for a part number for a power tilt switch for a 2007 nav.

 

I tried searching for you on www.partsguyed.com
Ed's a sponsor here. I could not locate your exact part in the steering column listings online. If you go to his site, register/create an account for free, and then send them a message with your VIN and what you're looking for.
They were great in helping me find the right window switches last week.
