Universal Radio Replacement Bundle

This bundle combines the iDatalink Maestro ADS-MRR interface with the HRN-HRR-AU1 vehicle-specific harness. It enables aftermarket radio installation while retaining factory features in select Audi models. The interface supports vehicles from 2003 onward and connects to compatible Alpine, JVC, Kenwood, Pioneer, and Sony head units.

For Audi Owners Retaining Factory Systems

This kit suits owners of 2004–2014 Audi vehicles who want to install an iDatalink-compatible aftermarket radio and keep steering wheel controls, voice commands, and the OEM amplifier. It is not for buyers whose vehicles fall outside the specified model years or who lack an iDatalink-ready head unit. Installers without access to the vehicle fit guide should verify compatibility before purchase.

Bundled Harness Simplifies Wiring

The included HRN-HRR-AU1 harness plugs directly into the Maestro RR or RR2 module and the factory wiring, supporting both amplified and non-amplified audio systems. This eliminates the need for cutting or splicing factory wires during installation. Optional head unit adapters are available separately for most major radio brands to complete the connection.

Questions about this item

Which aftermarket radios work with the iDatalink Maestro ADS-MRR interface in this bundle?

The ADS-MRR connects to iDatalink-compatible Alpine, JVC, Kenwood, Pioneer and SONY head units for full Gauges, Vehicle Info, Parking Assistance, Climate Control and Radar Detection screens. Basic steering-wheel and voice-command retention is also available with non-iDatalink radios.

Will the HRN-HRR-AU1 harness keep my factory amplifier when I install the bundle in my 2004-2014 Audi?

Yes. The harness is designed for both non-amplified and amplified Audi systems and retains the OEM amplifier when used with a Maestro RR or RR2 module.

How can I confirm the ADS-MRR is communicating correctly after installation?

After setup, the aftermarket radio should display the exclusive Gauges, Vehicle Info, Parking Assistance, Climate Control and Radar Detection screens, and the factory steering-wheel controls and voice commands should operate the new head unit.
