Add Wireless Bluetooth Audio Streaming to Your BMW 3 Series E46 — Connects via the CD Changer Port

Retrofit wireless Bluetooth audio streaming to your BMW 3 Series E46 with this hardwired adapter that connects directly to your factory radio's CD changer port and AUX input. No aftermarket head unit, no permanent wiring damage, no coding. Once installed, your phone pairs wirelessly and streams through your factory speakers every time you start the car.

Compatible BMW Models

Compatible with BMW 3 Series E46 models fitted with the Business CD or Professional radio with CD changer connector:

How It Works

The E46's factory radio has a CD changer connector at the back — even if you don't have a CD changer installed, this port is present on most Business CD and Professional radios. This Bluetooth adapter plugs into that connector and injects wireless audio directly into your radio's AUX input, while drawing switched power so it turns on and off with the ignition. Your phone sees it as a Bluetooth speaker and pairs automatically every time you start the car.

Key Features

• Wireless A2DP audio streaming — Spotify, Apple Music, YouTube, podcasts and more
• Powered by the ignition (ACC) — turns on and off with the car, never drains the battery
• Audio via the factory AUX input — clean signal through your factory speakers
• Hands-free calling (HFP) — answer calls through your car's speakers
• Auto-reconnect — pairs instantly with your phone every time you start the car
• No coding required — no BMW scanner, no software
• Compatible with iPhone and Android

Installation Guide — Step by Step

This installation requires pulling out the radio and accessing the connectors behind it. It takes about 30–45 minutes and requires basic tools (radio removal keys or a flat trim tool).

Step 1 — Pull out the factory radio
Use BMW radio removal keys (or a flat trim tool) to slide the radio out of the dashboard. Disconnect the existing plugs at the back and set the radio aside on a flat surface.

Step 2 — Connect the power wires
Locate the main wiring connector behind the radio. Connect the adapter's red wire to pin 5 (ACC 12V+, pink wire) — this ensures the adapter powers on with the ignition and never drains your battery. Connect the black wire to pin 15 (GND, brown wire).

Step 3 — Swap the CD changer connector
Unplug the existing red CD changer connector from the back of the radio. Plug in the new connector supplied with the adapter in its place — this is how the audio signal reaches your radio.

Step 4 — Connect the AUX cable
Plug the adapter's green AUX connector into the corresponding AUX input socket on the back of the radio.

Step 5 — Reinstall the radio
Slide the radio back into the dashboard. All connections should sit neatly behind the unit with no cables visible.

Step 6 — Activate AUX mode
Turn the ignition to ACC. Press the MODE button on the radio repeatedly until the display shows "AUX".

Step 7 — Pair your phone
On your phone, open Bluetooth settings and connect to the device named "sgbt…". Once paired, audio plays instantly through your factory speakers. Pairing is remembered — it reconnects automatically on every start.
