So after some reading, it seems it allows you to use the HU/steering wheel controls to control it. I was wondering if anyone had it installed, how you liked it and cheapest place to buy it. Also I saw you needed another part if the car has the aux, "(For models equipped with a standard “Auxiliary Jackâ€, an additional “Switch Boxâ€accessory, P/N C9F1-V6-261 is required, to allow both features to function.)" anyone know how much that costs?
