Just had UMI installed in 08 C300. Works great. Per the manual should be able to display nav info in the inst cluster. Figured out that needs to be activated via the Nav menu which I don't have. From looking at the owners manual that is part of the Command system which I don't have. Does/should UMI add this function? Per the dealer all software is at the most current levels yet I question if I should be able to display info in the inst cluster. While the manual says yes it's not clear that Command is a pre-req to make it work.

Other than that - A great upgrade!

Thoughts?
