You need the TMC tuner as well - that also converts the CAN bus from the Audi dialect to the Bosch dialect that the RNS-D uses.

Have you completely unplugged the old basic navigation? You must do that since they share the same address on the diagnostics.

Hi dave what should i disconnect from the basic nav,ie wiring under the centre console ,and where else,many thanks for the help.

It won't go past the key code as your wiring loom is missing the battery backup or SAFE feed, also you need an ignition feed and a lighting feed. Alo you need to remove the can bus wires from pins 7 & 12 of the 20 pin connector as they are the telephone connections on the RNS-D.

When you get a TMC module these two wires connect to the 12 pin connector on the TMC module.

You will also require a speed pulse or GALA wire connected to pin 1 of the 8 pin power connector and the ABS pulse of the 26 pin connector.


A whole lot of work if you ask me.

Second that,

I always think it's best to skip the RNS-D and retrofit an RNS-E...
