Section 1 RNS-E Navigation Headunit The installation of the RNS-E Navigation unit into a 2000-2001 A6 is a multi-step process. The main obstacle to overcome for this installation is that the original Symphony I radio is not CANbus (Controller Area Network) enabled. The vehicle has many CANbus systems, from engine management, to transmission control, to the one of interest here called “infotainment”.
Remove the center trim piece (1) between the steering wheel column and instrument cluster by pulling straight out. The picture shows the steering wheel removed. It is not necessary to remove the steering wheel for any part of this installation. Remove the driver’s side knee panel and set it out of the way. See the picture below. Remove the two Phillips screws holding the bottom of the instrument cluster. These are likely to be extremely tight. Use the proper size Phillips screwdriver.
To remove the instrument cluster screws, try tightening the screw first just to break it loose. The screw has a very fine thread pitch meaning the screw will not actually tighten much by being turned clockwise. Also, use an offset screwdriver for better torque. This method has worked for me numerous times. Remove the Symphony I headunit. Insert the four radio removal tools as shown.
1.1.1 Connecting to CANbus This step changes CLK and DATA wires that run from the cluster to the radio to CAN H and CAN L. This also accomplishes is the reassignment of the correct pins on the steering wheel control unit to be on the CAN network for proper operation. Refer to Appendix D for diagrams of the wiring changes outlined in Section 1. The steering wheel control module installation is covered in Section 3.
1.1.2 Mounting the GPS Antenna While the instrument cluster is removed, install the GPS Antenna as shown in the picture below. Extend the antenna wire from this location to the area behind the headunit. This is a proven installation location for almost every Audi vehicle. It will likely be necessary to fish the wire from the cluster area to the headunit area by accessing the area under the dash on the driver’s side.
1.2 Reverse Wire The RNS-E installation into the A6 requires that a separate connection for the reverse wire be made. This wire permits the RNS-E to know when the vehicle is in reverse gear so that it will move the indicator correctly on the map. Without this wire, the RNS-E will move the indicator forward on the map which will create a location error until the unit is able to synchronize with the GPS satellites.
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.
1.3.2 Plug-and-Play Wiring Harness This section describes a crucial step that is often overlooked during installation. The plug and play harness provides all electrical connections to an expensive electronic device that is likely used and carries no warranty coverage. The plug-and-play (PNP) harness is the easiest way to connect the majority of the wiring when replacing a symphony radio. This has two ends that will be referred to as the RNS end and the vehicle end.

1.3.3 Radio Antenna Adapter The Radio Antenna ends must also be used with an adapter harness in order to be connected to the RNS-E headunit. It is crucial to purchase the correct antenna adapter. Most antenna adapters that are supplied in package deals are used for upgrades from Symphony II radios and will not work for replacement of the Symphony I. The correct antenna adapter is shown below. Connect the two antenna leads from the vehicle to the antenna adapter. 1.3.
1.4 Control Module Coding (VAG-COM) The RNS-E and instrument cluster must be coded with VAG-COM to ensure proper operation. Connect a diagnostic cable to the vehicle and start the VAG-COM software on the computer. In leiu of using VAG-COM software, the vehicle can be coded at any Audi dealership. Expect to pay for this service. VAG-COM Release 512 is recommended. From the Main VAG-COM screen, press “Select” under the Select Control Module area.

To change the coding, press “Recode-07” Enter the new coding desired in the “Software Coding” box. Verify that the new coding was accepted in the “Open Controller” window. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
To change the adaptation values, press “Adaptation-10” Scroll through each adaptation channel that is listed in the chart below. Enter the correct value based on the vehicle charateristics. When finished, press “Done, Go Back”. The important channels are shown in yellow highlight. The remaining channels can be set via the menu system in the RNS-E itself.

The controller is restarted but fault codes are not cleared. -> Channel 114 (FM-Sender Status) On inquiry.
The last step is to get the instrument cluster adapted to recognize the radio and navigation data for use in the Driver’s Information System (DIS). This is the small red display at the center of the instruments. See the vehicle and RNS-E owner’s manuals for information on using the DIS once this installation is complete. Select “17-Instruments” on the Control Module Screen. To change the adaptation values, press “Adaptation-10” Do not Recode the Instruments It could cause a malfunction.
Section 2 Satellite Radio Module This section will describe how to install an OEM Audi satellite radio module in a vehicle that is not pre-wired for it from the factory. These instructions are specific to Audi vehicles with the CD Changer connection plug in the trunk. First, a note about this installation method. The SAT radio tuner uses the same wires to send audio signals to the headunit that the external CD changer (CDC) cable uses.
2.2 Power Wires The SAT radio tuner will be located in the trunk and needs a power supply there. Luckily there is a good source of power from the correct fuse (#37) already in the trunk: a 2.5mm wire that carries the power from fuse #37 to the amp on the right side of the trunk. Remove the trunk floor carpet and rear cross panel trim at the lip of the trunk. Remove the right side trunk trim, at least far enough to allow room to work with wiring at the amplifier.
2.3 Audio Wires The existing CD changer harness already contains three wires that take audio signals from the trunk to the headunit. This installation will take advantage of them. The CDC plug is in the left side trunk panel kind of tucked up behind the tool kit. It is a large plug wrapped in grey foam. Pull it out and remove the foam cover. The custom wiring harness created in this step will have a female 13-pin DIN plug that mates to the CDC trunk plug.

2.4 Data Wires Run two new wires (24 AWG minimum) from the headunit to the trunk. I did this by running a CAT-5 ethernet cable. This type of cable has 4 pairs of wires. Each pair contains a solid and a striped colored wire that are twisted around each other a few times an inch. This twist is also a standard of the CAN network. Even though only one pair is needed for this installation, it is easy to run the whole CAT-5 cable.
2.5 Antenna Wires With all the other wiring completed, the last step is the SAT antenna. The right antenna must be purchased for the SAT radio service planned for installation. The OEM Audi antenna will work for both SAT radio services, but requires a drilled hole in the roof to mount and the purchase of antenna cables and more connectors. This may be of interest to Avant owners that don’t have the mounting location of the sedans.
2.6 Completion In the 2001 Audi there is not a “factory” place to install the SAT tuner. A good location is the slot where the CDC goes, attached with a hefty dose of Velcro. A SAT radio mount kit is available, but it only consists of 4 screws and 4 plastic nuts that have no purpose if the vehicle doesn’t have the “factory” mounting position. Mount the tuner and plug in the antenna connectors, power connector T8r, and audio connector T8s.
Section 3 Multifunction Steering Wheel This section will describe how to change the multifunction steering wheel (MFSW) control unit to regain the use of the steering wheel controls with the RNS-E. These instructions are specific to vehicles with existing multifunction (audio/telephone) buttons on the steering wheel. The new installation of a MFSW into a vehicle with a regular steering wheel is far more complicated than the instructions given in this document.
3.2 Control Module Coding (VAG-COM) The new MFSW control unit must be coded with VAG-COM to ensure proper operation. From the Main VAG-COM screen, press “Select” under the Select Control Module area. Select “16-Steering Wheel” on the Control Module Screen The software is now connected to the new MFSW control unit in the “Open Controller” window. Note the Software Coding located just below the part number display. Check the chart on the next page to see what the coding means.
To change the coding, press “Recode-07” Enter the new coding desired in the “Software Coding” box. Verify that the new coding was accepted in the “Open Controller” window. Exit VAG-COM. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
Section 4 Bluetooth Telephone Module This section will describe how to install an OEM Audi Bluetooth telephone module in vehicles that are equipped with analog telephone preparation wiring. This analog telephone preparation consists of the handsfree microphone near the sunroof dial, and the wiring harness that ends in the trunk with a DB25 female connector. If the vehicle is equipped with the BOSE audio system, there will also be a small telephone audio speaker in the middle portion of the B-pillar trim.
Next, construct the custom wiring harness using the wiring connections shown in the chart below. The wire gauges are listed for information only. This is to prove that the wires supplied in the 25-pin telephone harness are of sufficient size when compared to the required size listed for the BT module. The parts required to make this cable are the 54-pin plug , 5 repair wires, and a DB25 (D-sub) male terminal with hood. These parts are shown in the surrounding pictures.
To make the harness, snip each repair wire in half. The pin terminal end will be inserted into the 54pin connector. The bare end can then be stripped of insulation and crimped into the small pins supplied with the male DB25 connector. These small pins may simply be snapped into the correct openings (based on the wiring chart) in the male DB25 connector. Once all the connections are made, the 54-pin connector can be assembled by sliding the blue inner portion into the black outer shell.
The Bluetooth module is shown below fully connected to the vehicle. The final mounting location is not shown, but a convenient location is on top of the satellite radio tuner, attached with Velcro. When mounting the BT module, ensure that the location is secure and that the antenna will not be susceptible to movement or actions that may cause damage. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
4.2 Connecting the K-line The K-line is an important connection for the BT telephone module because this is how it communicates with VAG-COM or other diagnostic software. Without this, the BT module will not be able to be coded to ensure proper operation in the next section. There is no K-line connection in the original DB25 phone connector in the trunk. However, there is a simple way to connect this without having to run new wires into the trunk.
Locate Connector T15s, the blue 15-pin connector near the top in this connection station. Pull this connector out to give enough room to disassemble the housing and change the wiring inside. Once unplugged, the top portion can be removed by sliding off as shown. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
Now the cover can be removed from the bottom section to reveal and unlock the wiring pins inside. Pin 13 in this connector is a small grey wire to be replaced. Simply use a small screwdriver or knife blade to disengage the locking tab on the grey wire and gently pull out from the rear. This will be very similar to the wiring in section 1.1.1 of this document to remove the pins from the 32-pin instrument cluster plug.
The final step of this section is to splice the other end of the repair wire into the K-line. The K-line is the small green wire that connects to pin 7 in the VAG diagnostic connector. In the picture below, a small section of the wire tape was removed a few inches back from the connector end. The small green wire was spliced using a red (18-22AWG) wire splice tap. Secure the repair wire by taping off to other wiring harnesses or by using cable ties.
4.3 Control Module Coding (VAG-COM) The BT module, RNS-E, instrument cluster, and MFSW must be coded to ensure proper operation. Connect a diagnostic cable to the vehicle and start the VAG-COM software on the computer. In leiu of using VAG-COM software, the vehicle can be coded at any Audi dealership. Expect to pay for this service. VAG-COM Release 512 is recommended. From the Main VAG-COM screen, press “Select” under the Select Control Module area.

To change the coding, press “Recode-07” Enter the new coding desired in the “Software Coding” box. Verify that the new coding was accepted in the “Open Controller” window. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
To change the adaptation values, press “Adaptation-10” Scroll through each adaptation channel that is listed in the chart below. Enter the correct value based on the vehicle charateristics. When finished, press “Done, Go Back”. Exit back to the main VAG-COM screen when finished. No adaptation values were altered for my installation. My speaker and microphone volumes require no correction.
The next step is to code the RNS-E to recognize the Bluetooth Module data over CANbus. The RNS-E unit must be running at least US firmware version 0110 for telephone functions to be activated. This firmware is on the North America Version 2A DVD. Select “37-Navigation” or “56-Radio” on the Control Module Screen. Either option will access the RNS-E for coding. The software is now connected to the RNS-E in the “Open Controller” window. Note the Software Coding located just below the part number display.
To change the coding, press “Recode-07” Enter the new coding desired in the “Software Coding” box. Verify that the new coding was accepted in the “Open Controller” window. Exit back to the main VAG-COM screen when finished. © 2005, 2006 Lee H. NSX JR – Audi Symphony I to RNS-E Install Guide – Version 2.
This step will adapt the instrument cluster to recognize the telephone data for use in the Driver’s Information System (DIS). This is the small red display at the center of the instruments. See the vehicle and RNS-E owner’s manuals for information on using the DIS once this installation is complete. Select “17-Instruments” on the Control Module Screen. To change the adaptation values, press “Adaptation-10” Do not Recode the Instruments It could cause a malfunction.
This last step will recode the MFSW control unit to enable telephone and voice activation operation. Select “16-Steering Wheel” on the Control Module Screen The software is now connected to the new MFSW control unit in the “Open Controller” window. Note the Software Coding located just below the part number display. Check the chart below to see what the coding means. If the coding is satisfactory, exit out of the VAG-COM software and skip the remainder of this section.
To change the coding, press “Recode-07” Enter the new coding desired in the “Software Coding” box. Verify that the new coding was accepted in the “Open Controller” window. Exit back out of VAG-COM completely and disconnect the cable from the diagnostics port. This completes the installation of the Bluetooth Telephone Module. © 2005, 2006 Lee H.
