I have an Alpine ILX-507 in excellent condition. I am wanting to trade it for a Kenwood Excelon 700 - 900 series or a Sony XAV-6000 or higher. The Alpine has 5 volt pre-outs with front, rear and subwoofer. 13 band parametric eq. It has a 7 inch screen with a single din chassis to allow room for cable storage. It has GPS, iPhone control, Android Auto connections through Bluetooth or USB. It currently has the back up camera and the parking brake by pass so you can play DVD's while driving (not recommended) also has HDMI connection with the HDMI to C adaptor, needs the additional Alpine connection. Will also control multiple cameras with the additional Alpine connection. Let me know if you have the radios that I am wanting or you can purchase the head unit for the listed price. This is still selling for $750 plus new or $650 used.
