I have a response!
Thank you for your email dated January 14, 2013, addressed to Mr Harkan Suleyman, Customer Service Manager, BMW Group UK. Your correspondence has been passed to me for an investigation and a response.
I am sorry to learn of your concerns regarding the Satellite Navigation system on your BMW 320d. To investigate this, I have taken the opportunity to contact Mr Mick Arnese, Service Advisor, Scotthall Milton Keynes. Mr Arnese has confirmed that your vehicle has been diagnosed, however, a software update is required to rectify the faults that you have experienced.
I can advise that BMW Germany is currently working to release the software update and Mr Arnese will contact you directly when it has been released.
In closing, I am sorry that you have had cause to contact us, however, I trust that this response is of use to you.
