Introduction:
Becker radio is popular in older European luxury cars (e.g. Porsche, BMW,
Mercedes, Land Rover, Ferrari etc.) and for those looking to upgrade to
Bluetooth without changing the radio, we offer the A2D-BKR Bluetooth receiver.
The A2D-BKR provides a Bluetooth Audio Streaming solution for any A2DP
Smartphones which then allows these vehicle owners to stream music without
wires. Most Phones with Bluetooth 2.x, 3.0 and 4.0 include the A2DP profile so
please check your phone to verify compatibility. Remember the A2D-BKR works
only on Becker Radios with an “AUX”Menu Option and replaces the CD
Changer (if present) however; to retain use of the CD Changer, purchase our
A2D-BKRCD instead.
See Frequently Asked question at the end of this guide for more details.
Installation:
Remove radio from dashboard to gain access to the connectors. A pair of
removal tools (See Fig. 1) is required to remove all Becker radios.

Frequent asked questions
1. My vehicle has a CD Changer. Does the A2D-BKR work in vehicles with CD
Changer?
YES; but the CD Changer, aux, iPod adapter must be disconnected.
2. Does the A2D-BKR work on all Becker Radios?
NO; Works on all Becker radios with “AUX” menu option. Becker radios without
AUX option (e.g. CR-210, CDR-210, CR-1 etc.), are not compatible, however if
vehicle has a working CD Changer, see our A2D-BKRCD
3. Do you offer an adapter that works on Becker radios that do not have “AUX”
input capabilities?
YES; Purchase our BLU-BKR2223 or A2D-BKRCD if equipped with a CD Changer
(CD Changer remains functional).
4. Can I control my Smartphone music from the radio buttons?
NO; you must continue to use audio device (e.g. Smartphone) built-in controls
and display to operate the device.

YES; more than one device (slaves) can be paired however only one connection
can be active at a time.
6. I’m getting noise that increases with engine speed. Is this normal?
If you experience alternator whine (increases with engine speed), we recommend
adding a noise filter (e.g. NF3A) to power/ground supply lines.
Here is how to add our Noise Filter:
Filter installs between Module and plug (Ro radio) as seen in Fig.7 (No need to cut
factory harness)
- If necessary, remove black tape from module installation harness
- Cut red and black wires about 2 inches away from 8-pin plug
- Connect red wire from module to red wire from filter (out)
- Connect black wire from module to black wire from filter (out)
- Connect like wire colors from installation harness to filter (in)

calls and audio streaming.
