QUICK START BLUETOOTH INSTALLATION GUIDE FOR BECKER AUX RAEADY RADIOS
Created March1, 2017
Revised: July 27, 2020

Introduction:
Many European vehicle owners want to keep their cars as original possible
including the Becker radio and with the A2DIY-BKR kit, these proud owners can
now link up their Smartphones for Bluetooth Hands-Free, music streaming
and AUX input. An optional 3Amp USB charging port is available to keep devices
fully charged as your drive. With included wireless remote, users can change
track, accept/reject phone calls, adjust device volume and also keep eyes on the
road as you drive. The A2DIY-BKR works only on Becker radios with AUX Menu
Option and able to retain CD changer (if present). Keep the radio and car you
love while enjoying Bluetooth features only available on newer cars. For more
details, see Frequently Asked question and comparison chart at the end of
this guide.
Installation:
Most Becker radios are coded and will not operate
without the code. Do not proceed to step 4 if radio code
is not available otherwise radio will not operate upon
reconnection.
Remove radio from dashboard to gain access to the connectors. Special
removal tools (See Fig. 1) are required to remove applicable Becker radios
(except PCM1)

Optional push-to-talk button with built-in microphone:
This option replaces conventional visor microphone and separate push
button shown in Fig. 7 and 8, as both are built-into a single button. (See
images below) which means the button can be placed on dashboard within
driver reach or custom installed nearby.
To install simply connect 1/8” plug to module “MIC/CTR” jack (See Fig. 9),
route to dash area (cable is 6ft. long); clean surface, remove tape backing
and secure to dash. (To add to cart, simply tap option on order page)

Optional USB charging port (For charging, not audio playback)
This optional “Fast charge”module provides a charging source for your
devices. Should you decide to add it, we suggest 2 mounting options:
A. Flush to dash/panel requires drilling a ¾” hole in the dash
B. Flush with Support bracket (use this option to mount USB terminal
wherever your installation demands without drilling)
Flush to Dash or Panel (requires drilling)
1. Drill a ¾” hole in dash or panel using a step drill bit or equivalent (See
Fig. 10)
