Sat Nav / Hands Free / Music

[DrPips]

Hi all, I currently use my iPhone 4 to play music using one of those gadgets that plug into the cig socket and the aux input in the glovebox. This works fine, but I'm getting the tomtom app to use for satnav and would like a way of integrating this all with hands free. I have a dash mount for the phone so the microphone will be close enough to pick up my voice, but I need a way for the caller to come through the cars Speakers. Car is a 2009 ford focus diesel with standard stereo.

What would the cheapest way of doing this be without pulling the car to pieces?

Thanks,

Dom

Installing a bluetooth unit is the easiest, but to be honest, the cheapest way would be to buy an aftermarket stereo, or wire up a parrot kit with streaming.
