paired but not connected

Hi there. I had problems connecting my new HTC Desire HD to my new Volvo V60 via Bluetooth. Both devices could see each other and would initially connect for a short time and even allow me to make a phone call but then they'd both develop amnesia and forget each other. The phone would say "paired but not connected". I tried several reconnections, reinstalls etc to no avail. I had been eagerly awaiting the official Gingerbread update as I won't root my phone (at least not till I'm more clued up) but neither HTC or O2 made any contact to inform me of availability. I was playing with the phone yesterday and happened upon the system update option and decided to see whether there was a Bluetooth update available. I couldn't believe it when I realised that Gingerbread was sitting there waiting to be downloaded. I installed it and no changes were made to applications already installed or settings. When I climbed in my car to go home the phone connected to the hands free perfectly! The first couple of times I had to manually tell the car to connect to the phone but now it does it automatically with no user intervention. Another bonus is that HTC Sync works properly on my work desktop. The phone would see the desktop and vice versa but they wouldn't sync but with Gingerbread they connect. My advice – get Gingerbread as soon as you ca
