B1 is for cars with Business Radio/Dash CD
C1 is for cars with NAV

I just implemented this with several hours of debugging :banghead:.

Now a word of warning: there is a bug in this diagram. In connector X14118 pin numbers have changed places. Correct numbering is: 1-Right, 2-Left, 3-GND. Pins are in correct order in the diagram but numbers are wrong.

This was quite annoing since having to read schematics in a work I've used to rely on pin numbers. Component can be drawn various of ways but pin numbers is something you should be able to trust.
