Got the job done yesterday by TCL Retro Kits in Sale and can say that the quality of install was perfect and the Bluetooth works exactly as though it was factory fitted.
I also got the iPod adaptor fitted at the same time replacing my CD Autochanger and this also gives me track information via my display between the speedo and rev counter
If you want Bluetooth in your car it is definately worth giving Craig a call. He covers down south as well.
