E39 - BMW Accessory Navigation System Speed Input Signal

Short Description
During the installation of the BMW Accessory Navigation System into E39 vehicles, the speed signal input (male pin # 3 in the connector X322) cannot be found. Since July of 1999 production, the separate speed signal (Speed-A) output harness has been eliminated from series production. The speed information is now made available to the connected control modules in the form of a telegram via the body bus (K-bus). By design, the Accessory Navigation System is not capable to extract speed signal information from the K-Bus.
