Voice Direction Interuptions Over Bluetooth Head Unit Or Parrot Car Kit Options

[Mrgoodge]

Hi

Im a newbie to the forum so please forgive me if this has been answered somewhere, as im sure it has.

Im in the market for either a new car head unit with bluetooth or a parrot car kit.

One of the things i want to do with either set up is pair my TT520 to it so i can get say, whilst i am listening to the radio etc, the tomtom interupt whatever im listening to and give me voice directions through the car stereos speakers.

Has anyone got their set up doing this?

If so, what set up, meaning head unit or Parrot car kit have you got?

Thanks
