Just wondered how many people did not fork out for the Audi Sat NAV, and added one after, if so anyone any ideas what ones work well with the Bose Speaker System and Amp that comes with the Symphony Radio and Black Edition etc?

I was told Kenwood seem very top end in this sort of equipment.

I want a HD system, one that I can add the Speed Camera Data Base, Bluetooth for Phone, IPod, USB input/SD input, will have to add a separate multi CD player
