BECKER ANALOG RADIOS WITH CD CHANGER CONTROLS (CDC)
Introduction:
Becker radios were standard equipment in many 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 new BT3-BKR Hands-free and music streaming module. The BT3-BKR allows Becker radio owners to hold hands-free calls, stream music application, USB charging port (2.4A) and track controls using the radio and/or steering wheel buttons. Remember the BT3x-BKR works on all Becker CD changer controlling radios (CDC menu option) and replaces the CD changer/AUX/iPod adapter (if present). To retain use of the CD changer etc.; purchase our BTH-BKRCD instead. Please read this entire guide including Frequently Asked question at the end.
Installation:
Remove radio from dashboard to gain access to the connectors. A pair of removal tools (not included) (See Fig. 1) is required to remove these Becker radios.

2. Does the BT3-BKR work on all Becker radios? NO; Works on all Becker radios with “CDC” menu option including CR-210, CDR-210, PCM1. If vehicle has a working CD changer, it must be disconnected or purchase our BTH-BKRCD
