Functioning 12-disc changer in trunk or hatch
Introduction:
If looking to add Bluetooth features to your American classic with trunk/hatch
mounted 12-disc changer should consider the A2DIY-C5CD Kit. This revised
easy to install kit is essential to adding Bluetooth features to the C5 radio.
This module sounds great for mobile conversations, streaming Pandora, Sirius
radio, Apple music, audiobook, podcast and more. The included media button
(remote) can be mounted on dashboard or steering wheel to adjust volume,
track selection and more. In addition, an optional USB charging port is available
to keep devices charged while on the road. Thanks to the A2DIY-C5CD kit users
keep the radio and CD changer while enjoying Bluetooth features only
available on newer cars.
Warning: A functioning 12-disc changer required for module to work.
If vehicle does not have one or if malfunctions; this module will not work.

Muting is only possible when radio is in “AUX/Bluetooth mode. If in AM/FM
mode; radio will not mute. Radio must be switched to “AUX” to hear callers
voice on car speakers.

10. My second phone does not pair or find Bluetooth module. Why not?
Ensure no other phone is paired. Allow module to enter “discovery” mode
at which point it is ready for pairing.
11. Will I be able to connect a flash drive to optional USB charging port?
NO; Optional USB port does not support thumb/flash drives. Charge only.
12. Will radio CD player or Tape player work after installing this module?
YES! The CD player or Tape player built-into AM/FM radio or remote 12-disc

13. Callers not able to hear my voice with top down (convertible).
Can you offer some guidance?
In convertibles, microphone mounted to visor is exposed to wind noise.
Notable, callers will have no issue while vehicle is standing still. Our
microphone includes noise cancellation features, which is different than
wind noise and our recommendation is to install microphone in an area less
susceptible to wind noise (e.g., pillar, mirror etc.).
14. How do I remove radio from dashboard to install module?
The ADIY-C5CD connects to the radio. Click link for video instructions:
