New to this forum. I have read a lot of threads and found them helpful. Great info here. I have an 03 Navigator Ultimate Package with 57,000 miles. No GPS. I want to install a Pioneer avic d3. Any comments or infor would be appreciated..

My "check park assist" warning comes on when in reverse, Im assuming its a reverse sensor. Where can I get one? Does it have to be from factory?

Also, I have a lot of wind noise coming in from the drivers door when going over 60mph. I tried foam weatherstripping from home-depot all around the door but does no good. Any suggestions or help? Im even considering putting silicone around the edges. What do you think?

Anyway, I would appreciate some feedback. Im glad to be a part of this forum.:)
