BLU-BKR235
Quick Bluetooth Installation Guide for Becker AUX Ready Radios
Created June 19, 2015
Revised: February 13, 2020

Introduction:
Thanks to the BLU-BKR235 Kit you can keep the radio and car you love while
enjoying Bluetooth features only available on new cars.
With Bluetooth Technology and your Smartphone's Voice Recognition application
(Siri or Google Now); you can initiate hands-free calling, launch Navigation,
music streaming or any other application. One button (conveniently installed on
the dash) does it all. The microphone captures your voice commands and allows
your phone to make calls and launch important applications.
Installation:
Although not critical, we recommend disconnecting the car
battery. Keep in mind that most Becker radios are coded and
will not operate without the code. Radio code must be
available for radio to operate upon reconnection.
Remove radio from dashboard to gain access to the connectors. This
process requires special removal tools (not included) (See Fig. 1).
