E60 BUSINESS Sat Nav Update?

[shepster]

Hi All,

First time post... all help gratefully received!

I have a 2004 UK E60 with the BUSINESS sat nav system (arrows not maps.) I would like to update it with the latest map info and preferably with both 7 digit postcode searches and TMC.

Can anybody tell me whether this is indeed possible? And if so where I can get the relevant map info/software?

Thanks in advance for all your help.

Cheers,





Shep
