Right now I have a FX4 without nav. Im looking to put a nav system in it. any suggestions because companies around me told me this truck has not found a nav system that fits this truck.

 

I have an FX2 and have been looking to do the same thing...as of right now it looks like the only way to get nav is to take it out of a truck that has it lol... but if you find out a hu then let me know.

 

you can buy aftermarket nav system and put it in. i have a pioneer avic head unit in my truck and it fits just fine

 

The only thing about aftermarket is the dash kits dont match the FX2-FX4 interior and you lose a bunch of buttons which are used for sync and satellite radio I believe. It kinda sucks because I would have a new head unit in already.

 

I know you are looking for built-in nav, but if you can't find the dash kit/head unit, there was a post on here about a very clean way to mount a GPS where the coin holder is.

 

do you have any pics of your head unit?

 

not a real great pic but all i had time for before work........you can see the fitment anyway

 

here are a couple more pics i found on someones profile on f150online.com. He said he got the kit painted at a dealer though so it is matte originally.

 

Here's the manual for the Metra adapter kits (who usually makes one for everything) and how it works. Buttons swap over, etc.
