Upgrading OEM BMW E46 radio head unit with an AUX Cable:

What draws many people to the older BMW models is the pure driving experience that cannot be replicated by modern cars, some even say by BMW themselves. If you own an E46 you know what I am talking about. It is possibly one of the greatest 3 series ever built. If you daily one you may be frustrated by the lack of modern options to be able to play music from your phone through the OEM radio. CDs and Cassettes have their limitations and do not allow the versatility of having any song at your fingertips like modern phones. Luckily, BMW has a retro fit kit that allows a more modern functionality to the OEM radio.

Obviously, there are options to replace the entire head unit with modern features such as Bluetooth, USB, WiFi etc. Although this is an acceptable solution for some people, it isn't one all E46 owners want. The downside to this are the modern head units can be pricey, you have to cut/splice into the OEM wiring harness, they do not look as clean on installation and the glow the colors at night which is distracting and takes away from the clean OEM look since they often do not match.

The clean, OEM BMW solution:

BMW has created a retrofit kit which allows owners to use the OEM BMW Business radio head unit and install an AUX cable off the back. This keeps the OEM radio harness intact, the clean look and the natural orange glow of the buttons at night to match the rest of your interior.

NOTE: The kit comes with an AUX port only, this allows for the user to stow away the actual cable until needed and plug it into the port when wanting to use it. Many owners opt to not mount the port, but keep an AUX cable permanently installed into the port and feed the AUX cable under the center console for a clean look (see picture below).
