I had one in my car from Halfords years ago probably about £100.00 It was great , but, when I changed my phone I had to source another lead and when I changed my car I had to have it removed and then refitted.
I now have a Parrot which clips to the sun visor and have found it works really well. All you do is switch on when you get in the car and it marries itself to the phone immediately then to answer the phone you just press the main button. Bought it from Halfords for about £49.99. The good thing as well is if you have access to a couple of cars you can just take it into the other car when you go. I sometimes use my husbands car and it is so easy to move. As long as your phone has Bluetooth it is a doddle.
