I am using the standard Concert system on my 2006 A4. It has Bose setup. I am looking for the cheapest option to get handfree working in the car. This of course using the existing speakers.
I have looked into getting the Audi OEM interface which is pricey ££ and means I should be able to use my steering wheel controls.
Would changing the headunit (with various adaptors for amp, steering wheel etc) give me handfree functionality? Are there any head units that solve this problem?
