I'm able to get my hands on a 2015 Fit EX radio With navigation. Would it be easy to swap out my 2016 Fit EX radio without navi and replace one with navi from the previous year?

 

I can't speak to how much or little of a plug and play swap this will be.

But do you have the code for the 2015 Fit EX radio with navigation?

 

any follow up on this ??? im in the same boat and dont want to take it all apart.
I have the code for the new radio, but people keep saying the VIN will not match on the HU >?? not sure about that lol.

If we have the unlock code, im not sure if the vin will lock out the unit.

As as side note, the plugs at the back of the navi and non navi ex head units (7" touch screen) are identical lol.

So aside from maybe missing a few antennas, it looks direct PNP.
