I personally installed the kit myself in my BMW. I can say that I have been doing this kind of work for a while and it isn't a walk in the part. I wouldn't try it unless you have good knowledge of wiring systems in cars and how to dismantle your car properly(no breakage). As for the functionality of the kit: the only thing I don't like about it is how hard it is to snap the phone in while you are driving. It takes both hands, literally. The mic picks up wonderfully and the voice is very clear through the speaker. (...) It wows everyone that gets into my car. I would have to agree that this kit makes it much safer to drive since you can keep your hands on the wheel. However, I would also agree that the conversation, in large part, is what causes people to not pay attention to the road, not actually holding the phone itself. With laws coming down from New York that require you to pull over to use your non-hands free cell phone, I would definately recommend this product...that way you can keep talking on your way to your final destination.
