its not too bad, get a metra 99-5805 its a univeral ford double din kit. simply attach the radio into the kit, pull off your dash and cut the little lip off the inside of the hole, leave about 1/8 inch on the sides for the brackets to hold on to, then you just run some SHORT screws into the side of the attached metra brackets to hold it to dash and voila your done. and for your questions on install price, my shop for instance would charge $175 for a double din nav radio and $65 to modify your dash
