I hate when they make these stupid little changes between years, now I've got my entire interior ripped apart and I can't finish, because of a stupid antenna adaptor. I hope best buy stocks the adapter.

 

They will stock it! It's a Dodge/Chrysler antenna connection that was adapted over to Ford/Mercury. You will find that it's a very popular part number and every car stereo store in town stocks it. You will find it easy.

 

I have a 2005 GT and I did not require any adapter whenI installed the system. It plugged right in!!!
