BMW DSP Conversion kit

In stock
-- OR --

If you have a BMW that has the DSP (Digital Signal Process) option installed then you need this kit to enable a Grom Audio integration kit to function correctly.

This part is required in ADDITION to our BMW AUX1, IPD4, BT3 or USB3 kit, for a successful installation with the BMW DSP system.

Will also work with other aftermarket CD changer emulators.

Certain BMW's were equipped with what is known as Digital Sound Processing (DSP). DSP is a RG174 coaxial input instead of wires from the BMW CD Changer into the factory amplifier. BMW sometimes refers to this as 'premium sound'.

Vehicles with DSP as an option:

  • 1997-2003 5-series
  • 2004-2009 X3
  • 2000-2006 X5
  • 2003-2009 Z4

Vehicles with DSP as standard equipment:

  • 09/1998-2001 7-series
  • 2000-2003 M5
  • 2000-2003 Z8

Vehicles manufactured after MY2002 will have to inspect their connections to determine what type of DSP is present. If the vehicle was
originally equipped with a CD changer, you simply need to check the CD changer connectors.
If the vehicle was not equipped with a CD changer or the vehicle was purchased used (possibly the changer was removed by a previous owner)
you will need to locate the factory amplifier and inspect to see if the coaxial wire is present.

If you should need additional assistance, please take pictures of the amplifier and CD changer connections and email direct to us for confirmation.
