Sat Nav Mk3
 

Hi, just bought software upgrade V27, downloaded OK but it is asking for Key-CD ? Drawn a blank at BMW, they say the MK3 can't be upgraded, but my research says otherwise. Any ideas out there !!

For a MKIII, V26 is the highest I believe you can go without having problems.
I'm sure someone will chime in to verify. What features are you trying to obtain by going to V27?...........Phil

Main reason is to obtain UK postcode search & update street maps by using the 2006 nav cd which came as part of the package. Martin

You can download the KeyCD from the bmwnav Yahoo Group. I can also send you a link to download it from here later today.
