I have not seen any significant upgrade and hacking information for the E60 and E90 systems yet. The challenge is that they are significantly different from the navigation systems in the E38/E39/E46/X3/X5/Z4. They are even quite a bit different from the E65/E66 systems. The big difference is that the E60 and E90 systems get their software updates directly from the ProgMan computer rather than from an OS update disk inserted directly into the navigation computer. As a result, the software updates are not readily available to the common man for dissection and analysis. Furthermore, most E60s and E90s on the road are still under warranty, so very few folks have even had the need to tackle updates on their own. As you have probably discovered, most of the E60 and E90 discussions are about which SW versions are the latest and how to get the dealer to upgrade them for free.

I do not mean to be a total discourager, so keep on looking. I just wanted to offer my thoughts on why there is so little upgrade and hack information out there.
