I've used Clarion, Sony, and Pioneer head units in the past. I am not interested in adding a subwoofer, or amplifier, I just want to upgrade to a double din unit with in-dash navigation, AUX, and back-up camera possibilities.
dont waste your money. look at alpine kenwood and pioneer in that order. I have used a few boss products and its hit or miss, half of them function but not well others die after 6 months. alpine has been the best about user friendly head units in my experience.
