iDatalink's HRN-SR-AU1 wiring adapter works in conjunction with iDatalink's Maestro ADS-MSR Module, allowing you to connect a new car stereo in select 2002-07 Audi vehicles. Once connected, you'll retain the use of your steering wheel audio controls in these vehicles.
The package includes connectors that plug in between the Maestro module and your factory radio's wiring plugs.
