Just recently picked up a 2014 limited 4x4 non EL. So far love it. however I have questions.
Has anyone switched out the stock radio and navigation unit for an aftermarket unit? Not looking to rattle windows because after all it is a family transporter but would like something with a little more power and better sound.
Fog lights. After having to replace the fog lights on my 2013 focus i can only assume the same will need to be done on the expedition. Will a replacement Hella or PIAA unit work as long as it's the same dimensions or is a specific unit required?
And finally the always debated intake and exhaust. Have you guys messed around with these to try and squeeze maybe a little better mileage out of this gas chugger?
Thanks in advance
