I have been looking for something along those lines to replace the Pioneer whose Bluetooth stopped working just out of warantee.
I am not sure you can get a single unit that does the lot I'm afraid, unless you go to one of those far east, eBay specials.
I am currenly deciding whether DAB in the car is all that useful given coverage etc, but bluetooth is a must, as well as some aux in/iPod controller, or even better, USB & a pocket hard drive.
If I can live without the USB and DAB, I am looking at a Becker Grand Prix (As they come with yellow display to match the coop!!), or a JVC KDBT1 as they have USB, BT and you can get a DAB & iPod interface with them as well.
Cheapest I have found the Becker is £250, and the JVC is £180, or £299 with DAB and aerial, or £340 with that and the iPod.
