Hi

Im new to this forum but have had my B7 SPORT 170 since may last year (Think i was one of the first in the country to get one).After upgrading my nokia to an iphone 4s im having no end of trouble with my standard RNS 315,i can make outgoing calls but as soon as somone calls me the bluetooth drops completely ..stops the call.. and the only way to reconnect is to turn the bluetooth on and off on both the car and the phone. Any thoughts? Oh yes and its silver and the paint has started to fade in places and its only 15 months old!!
