Product Research


Vehicle Compatibility: The AX-BM90122 radio replacement interface module from Axxess Integrate allows you to replace the factory radio in select 2004-2013 BMW vehicles featuring a stock M.O.S.T. 25 amplifier with an aftermarket head unit while retaining important factory features.

Retained Factory Features: The Axxess Integrate AX-BM90122 retains the following OEM features in your vehicle after you have replaced your factory radio with an aftermarket head unit.

  • Factory Amplifier & Audio Level Adjustments: The Axxess Integrate AX-BM90122 retains the vehicle's factory M.O.S.T. 25 amplifier with balance control. Fader control is not supported.
  • Steering Wheel Controls: If your aftermarket head unit is steering wheel control ready, the included ASWC-1 steering wheel control interface module and harness allow you to retain your vehicle's factory steering wheel controls.
  • Factory Display: The AX-BM90122 also retains factory display of date, time, and temperature.
  • R.A.P. (Retained Accessory Power): The AX-BM90122 retains the R.A.P. function in your vehicle. R.A.P. (Retained Accessory Power) supplies power to the radio after the ignition is shut off until one of the front doors are opened.
  • Warning Chimes: In addition, the AX-BM90122 will retain factory warning chimes when present in the vehicle.

Outputs: The Axxess Integrate AX-BM90122 provides a 12V/10A accessory output, illumination output, and navigation outputs to make installation easier and less time consuming.

  • Accessory (12V/10A): Because there is no 12-volt accessory wire in the factory harness of your vehicle, the AX-BM90122 provides a 12-volt, 10-amp switched accessory output. This prevents you from having to run an accessory wire to the fuse box or underneath the steering column when installing your aftermarket stereo.
  • Illumination Output: The AX-BM90122 also has an illumination output if your new aftermarket head unit has an illumination wire.
  • Navigation: The AX-BM90122 provides essential wires required for aftermarket radios that have navigation. VSS (Vehicle Speed Sense), Reverse, and Parking Brake wires are provided. This helps to cut down the installation time, since the installer does not have to look for or tap into these wires in the vehicle.
