BECKER ANALOG RADIO WITH AUX MENU OPTION
Introduction
Becker radio was standard in many European luxury cars (e.g., Porsche, BMW,
Mercedes, Land Rover, Ferrari etc.) and those looking to upgrade to Bluetooth
without changing the radio, we offer the A2D-BKR Bluetooth receiver. The A2D-
BKR allows these radio owners to stream music application from smartphone
without wires. Optional aux input jack can be added to which users are able to
connect and play portable audio devices such as MP3 players, iPods etc.
Remember the A2D-BKR works only on Becker radios with an “AUX”Menu
Option and replaces the CD changer (if present). 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.
