I'm thinking about buying a new double din headunit for my car.

Ideally it needs to have bluetooth handsfree built in and also a satnav. I also wouldn't mind having the ability to listen to DAB but those units seem to be much more expensive.

I have no clue really about what is good or not and what sort of money I should be paying?

Here's a couple I've been looking at, but again I don't know if they're what I need?

Also is having DAB worthwhile and how good is reception while driving?

Thanks in advance, Rob
