Got a portable music player? Then you probably know that a direct connection to your vehicle's factory radio will give you the best possible sound quality. The Precision Interface Electronics BMW-AUX adapter lets you add an auxiliary input to select BMW and Mini Cooper factory stereos, so you can connect a Dock & Play satellite radio, portable music player, or other audio source directly.

The adapter includes a harness that connects to the 3- and 6-pin connectors on the back of your factory radio. Warranty: 1 year.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle.

Features

Overview: DPX Auxiliary input converters by PIE (Precision Interface Electronics) are designed to convert the CD Changer port of the OEM radio (with CD Changer controls) into an auxiliary input. Devices such as Satellite Radios, DVD Players, VCRs, MP3 Players, and Game Systems can be added to the OEM radio without an FM Modulator. DPX Technology maintains full function of all factory steering wheel and rear seat controls.

Compatibility: The BMW-AUX allows you to add an auxiliary input to the factory radio in select 1995-up BMW vehicles. The adapter connects to the 3-pin and 6-pin CD changer cables found in the OEM CD changer location (even if there was no OEM CD changer), avoiding wire splicing and modifications.

  • BMW 3-Series (1998-up)
  • BMW 5-Series (1995-2003)
  • BMW X5 (2000-up)
  • BMW Mini (2002-up)

Note: The adapter takes the place of the factory CD-changer, so you cannot have a CD-changer and the adapter connected to your factory radio at the same time.

Mounting: The adapter can be secured to any flat surface using the module's integrated mounting flanges and optional mounting screws (not included).

Connections: The BMW-AUX features a female RCA input to connect your portable auxiliary audio source. The auxiliary input interface also features proprietary 6-pin and 3-pin jacks for connecting the BMW-AUX to the 3-pin and 6-pin cables in the CD changer location.

IT WORKED!!

Written By Leland, FL on Thursday, October 25, 2012

Crutchfield Customer Review (What's this?)

It was easy to connect to the 6 and 3 pin connectors and took about an hour to run the RCA cable to the front of the car into the console and connect a sat radio. It's a basic use item, but it does what it is advertised to do.

Pros: Easy to connect

Cons: Would be nice if it included Bluetooth

Great!

Can't ask for any better solution. I contacted Lyle @ crutchfield and he was very knowledgable with this item. Place my order and it arrived as described and fast. This adapter plus Y RCA to audio cable is all you need. For all BMW e46 drivers with or without cd changer , this item is plug n play and will get your mp3 player jammin in your ride. Buy it!! I'm 100% satiates fixed and could have not found a better solution.

great alternative

CD quality is what you get with this product, very easy to install, the only negative is that it doesn't come with RCA cable, they have to be purchased separately.

Simple solution

Crutchfield Customer Review (What's this?)

I sought a simple solution for years for auxiliary mp3 input in my 2001 BMW 5-
series. This little device does the trick. The instructions are clear, the hookup was
done in a couple of minutes. The most time-consuming part was taking out the
back seat to run the audio line, but even that was easy once I found a YouTube
video demonstrating that. Works great--CD quality music for road trips!
