Activate Nav System
 

I purchased a new 2013 f-150 eco last April. It is nav capable but it doesn't have the chip.The dealer said I could buy the chip and it would work. Do I have to go thru the dealer or can I buy one on Ebay and install myself. We just bought a 2014 Edge yesterday and it has nav activated. Can I use that chip in my pickup? Thanks in advance, Dave
