Thanks, I remember having a similar issue on my e60 - also it led to overheating of the unit, ended up buying a damaged radio on eBay and replacing the fan, it was not complex but a lot of small parts / screws to get to it...

I'm getting nervous on the Airbag recall but not sure what is going on as I keep getting letters telling me that parts are available, etc etc. seems I'm on th outstanding cars list.....

Hope you get your stuff fixed....

Thx
