Hello All,

I have a 2006 X5 4.4, my nav is SW4-1/60, I am not sure which version this is.
the nav disk is 2005.2 North America. The navigation is extremely slow and the nav disk is out of date. Could someone point me in the right direction as to how i would update the OS on the nav. What version should i put on and how do I do it myself. Also are the disks available somewhere to download.

Thanks for all the help.

Robert
