I have two phones (work & Private) that I use with the Bluetooth Handsfree in the car, I switch between the two phones depending on whether I am out for business or pleasure. When I first got the car I had a SE K750i as a private phone & a Nokia 6230i for a work phone. both of these phones linked to the car & all the contacts showed correctly. A few months ago I changed the K750i to a W810i (very similar phone) again everything worked fine but recently within the last few weeks I have found quite a few contacts in the W810i do not show on the car. I know that the car is meant to automatically update new numbers but does not seem to happen, I am thinking I may need to clear the car memory & start again? does anyone have any advise on how to sort this out?
