I'm looking at getting a hands free kit for the wife, she's a district nurse and often has people ringing her whilst she's driving, I've never had anything to do with this type of product before so am a bit clueless. I've heard of Parrot but how do I integrate it into the existing stereo, the car is a 2003 Renault Megane? The current stereo is sometimes temperamental playing cd's so would another option be to buy a new headunit with built in hands free, is there even such a thing? I would like to keep the steering wheel stalk controls working and separate display if possible. Any advice would be great because like I said I haven't the fogiest when it comes to all this.
