Who we are

About Us

This is a hobby project by pcbbc, an Audi TT and RNS-E enthusiast.

Driven by his goal of retro-fitting a 193PU RNS-E into his Audi TT 8N, a vehicle which was only rarely fitted with a BNS navigation system from factory, pcbbc has fixed bugs and added extra features to the stock RNS-E firmware.

Lots of the features we have added, and bugs we have swatted, are equally applicable to other RNS-E equiped vehicles. So we present here a modified version of the firmware for your own use.
