I rate the radio 5 star. Ipod interface 5 star. xm interface 5star. Now for the Nav system if I could give it a -5 stars I would. I have used them all in rent a cars and own an old garmin that works great. The D-3 has a habit of routing you pass were you should turn and than will have you u turn and back track up to 3 or 4 mile to turn on the street you passed 5 miles ago. It is 4 house off to find my house, the old Garmin is 4 feet off. For Navagation forget this one.
