I used to have a clarion. One of the most trouble free decks ive had. Its about 6 years old and still going strong in a friends car. The new ones are supposed to be very nice. Id consider them before blaupunkt. I dont know whats going on with alpine, yanking the 4v outs excpet for the 9855. Ive played with the glide touch and wasnt too impressed with it either.
