It's a W925R double din head unit which does sat nav/ DAB/IPOD and Bluetooth phone. It also comes with the Alpine reversing camera.. To go with the unit there is a Rainbow Beats 2 amp so you get the best sound out of it. It also has a silver 997 surround. It comes with all the cables to connect it into a 997 with the ASK optical set up. It's less than 12 months old and only selling as I have sold the car. Original set up cost £1500 plus fitting. I'm selling for £600.
