1.3 Headunit Installation

The subsections within this topic will describe how to complete the physical installation of the RNS-E

headunit. To continue from this point, Sections 1.1 and 1.2 must be complete.

Before performing the work in this section, the original satin black climate control faceplate may be

replaced with a faceplate from a 2002-2004 A6 to match the flat black color of the RNS-E. Since this

step is not required, further information is located in Appendix H.

1.3.1 Connecting to CANbus

Obtain a terminal extractor tool to make this section a snap. http://forums.bostonaudi.org/viewtopic.php?t=3945

In the area behind the headunit, locate the black (or multi-colored) 20-pin connector. This is officially

named Connector I. The pins in this connector are smaller than all the other connectors. The purple

sliding locking bar does not completely come out of this connector, but it must slide out as far as it

will go before moving any wires. The vehicle may have the three colored pieces that all snap together

to form one instead of the black housing. See the picture below for comparison of both types.

Remove the CLK wire from Pin 8 of Connector I and reinstall into Pin 7 (CAN H) of Connector I.

Remove the DATA wire from Pin 9 of Connector I and reinstall into Pin 12 (CAN L) of Connector I.

Slide the purple locking bar back into its closed position.
