Have Sony's head units gotten any better in the past years? (xplode era left a bad taste in my mouth) . I have the chance to get a mid line Sony single DIN head unit (Bluetooth, dual usb , remote, satellite radio) with steering column remote, wireless remote, and CD changer basically for free. A friend of mine got a new car and she can't figure it out, so she wants to trade for the 15 year old Kenwood unit in my truck which is easier to use (she doesn't care about features, just listening to the radio).
