Becker A2D-BKR Quick Start Installation Manual Download Page 2

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.
