Like this http://astrium-electronics.com/ford-gee-2865.html I like it because it looks factory, they say they program it to match your factory system ad it is plug and play. It has pretty good reviews on the Dodge forums but I can't find much of anything on a Mustang. It is a Toronto company and you can buy these radios for 450 on kijij. http://www.kijiji.ca/v-car-audio-gps...ationFlag=true
