In regards to the factory Sony NAV unit found in the 2011 Lariat.

On the back of the 7" screen, there is a large gray block plug and next to it a gray or white small diameter plug of some sort - can someone ID what these two connect to?

I'm trying to figure out if a swap into my FX4 is possible.

Thanks for reading!

 

Hope this helps.Better late then never.

 

Thanks for the info - came down to it and we looked at the schematics of the wiring harness under the dash on both my truck and one from a same model and equipped the same (sans nav) and there was ONE plug my harness didn't have that the NAV needed.

Abandoned the idea. Bummer but not that huge a deal really.

Thanks though.
