Hello,

Does anyone know how to select the aux in as source? Which button do you have to press (or press twice like on a becker mexico).

Does anyone know which brand the RNS-e is? (sony, blaupunk, becker)


THanks!

The RNS-E ist made by Aisin and nobody has so far figured out how to use the AUX IN pins in the 32 pin connector.

My dealer told me:

To enable aux in: press the cd button twice.

I will test it today.
Another dealer getting confused ....

IF you have a Symphony II+ AND it has been coded to enable the AUX IN input, then the dealer would be correct.

BUT, neither of those "IF's" apply to an RNS-E!!!

Pressing the CD button twice on an RNS-E fitted with a TV tuner will enable the TV tuner...

I got this from a site and if you have firmware 260 you should be able to do this.. Ignore the firmware 650 becuse its a eruo version but the steps should be the same

If you already have RNS-E and want to add AUX you will need the following parts:

OEM Aux-in 3.5mm plug (8J0 035 475)
4 pin harness that plugs into Aux-in plug (8E0 973 754)

**If you don't need the OEM look, just buy any 3.5mm plug, RCA plugs, or even an ipod dock plug, depending on what you want to connect.**

Grey 32 pin AV connector for RNS-E (1J0 972 977 G)

3 female repair wires for the 32 pins AV connector (000 979 009)

Aux In Left - pin 22 of AV Connector
Aux In Right - pin 6 of AV Connector
Aux In Ground - pin 21 of AV Connector


Recode the RNS-E to XXXXX?X to enable Aux input using VCDS (vag-com)

? = 5 to enable AUX only
? = 6 to enable AUX and SAT radio

This mod will also work with Symphony II+ and Concert II+ head units also. Just look on top of the head unit for the pin-out diagrams and connect accordingly.

On the 2009 A3's, Aux is already installed standard. If you want to upgrade to an RNS-E from a Symphony or Concert head unit, all you will need is the 32 pin A/V connector, swap 3 wires from the Aux-in. If you have Bose, an additional wire swap is need to ground the Bose.

All these parts can be sourced from your dealer for relatively cheap. No need to order from Kufatec or Vagparts (no longer an option anyways, they are closed).
