Its a little more detail that that. Its not as easy as peeling the sticker and switching the switch. You have to rigg up a paperclip. You should take it to a radio shop that does installs. They charge almost nothing and you know your not going to mess up the radio.

yes you need the GPS antenna

yeah, u need the gps antenna to get the speedo b/c it works off of gps locations, not the speedo in ur car. my gps speedo reads 2mph slower than my truck speedo and i trust it more than the truck speedo.

^^I trust that speedo more then my car one as well. OP, like has been said above you needd to hook up the GPS antenna. They're cheap. Something like $30 in the classified's.
