It will probably include the GPS antenna, but you'll have to ask the seller.

It's really not worth it to do the install though. Get an aftermarket GPS headunit. To get stock navi working, you'll put a good 8-10 hours to do the install, lose your top glove box, have outdated maps, and you'll be tied to the stock headunit, which is very prone to failure with rather expensive repairs.

You take a huge chance that those include a full enough wiring harness to actually install it too.

Take some fairly-expert advice here, and just don't do it. You can put a garmin in the top of the flip-up cubby hole that'll be just as clean looking, 1/4 the price, install in 5min, be more up to date, more accurate and can be removed and taken with you on trips.

 

thanks so much i wont get it. small garmin gps will do just fine

 

yea dont even waste your time. I have an 05 coupe w/navi. Its not worth it. Interface is so dated.
