QUICK START BLUETOOTH HANDS-FREE INSTALLATION GUIDE FOR SELECT 1997-04 CORVETTE WITH 12-DISC CD CHANGER
Created January 16, 2013
Revised September 9, 2020

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 wireless remote
control can be mounted on the dash or steering wheel to adjust volume, track
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.
Trunk/hatch mounted 12-disc changer is required. If
vehicle does not have one or if malfunctions; purchase our
A2DIY-C5 instead.
See Frequently Asked question at the end of this guide for more details.

This option allows users to connect and play a portable audio device (e.g.
sat radio, Alexa, iPod, Mp3 etc.) instead of 12-disc changer)

5. Use visor clip to install microphone on headliner, route cable down
pillar, under dashboard toward module location and connect to module
“MIC” input.
The microphone incorporates noise filtering; however wind noise
(Convertibles) will negatively affect phone calls. Instead of sun
visor, convertible users are advised to locate alternate location
for microphone. Also ensure no ventilation duct is pointed
towards microphone.

Revision (4.6.20)
what’s new:
1. Bluetooth playback is now possible up and until radio turns off.
(Previous revision would turn on/off with ignition switch).
2. No longer requires routing accessory wire to fuse panel.
Special circuit added to harness which powers module when radio is turned
on/off.Skip to “Optional USB” page 5
Modules purchased prior revision (4.6.20); proceed to step 6 below.
6. Connect (Tap) installation harness red wire to an ACC (Accessory or
switched) 12V supply power source in vehicle.
7. Connect red wire to accessory supply in your vehicle.
Optional push button with built-in microphone:
This option replaces standard visor microphone and separate push button
shown in Fig. 6, and combines both in a single button. (See images below)
which means 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, 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)

Where to get 12 Acc. supply:
1997-03: Many have a 3-pin plug under passenger toe board near BCM (may be
covered in black duct tape) -- See Fig.8 Yellow wire is ACC. If vehicle does not
have 3-pin plug; go to Alternate 12V Acc. supply below.
Fig. 8
Note: 3-pin plug may not be present in all vehicles.
Alternate 12V Acc. supply:
Fuse #22 or #11 of interior fuse box which is located under
passenger toe board (See Fig. 9).
The add-a-fuse mini-tap circuit seen in Fig. 9a is included for this purpose.
Fig. 9
How to use Add-a-fuse circuit
a. Strip 1/4- 3/8” insolation from end of accessory wire.
b. Look inside blue connector where metal ends. (useful in step d)
c. Insert stripped wire to blue connector
d. Hold wire in place and crimp down (crimping tool or plyers). After
crimp, pull wire to verify crimp integrity.
e. Remove fuse #22 or #11 (if present) from vehicle fuse box otherwise
skip to step g.
f. Insert factory fuse to empty slot on add-a fuse circuit (See Fig. 9a)
g. Insert add-a-fuse circuit to fuse box slot #22 or# 11
Noteworthy: If there is no fuse in slots #22 or #11, the fuse slot on add-a-fuse
tap remains empty. (See Fig. 9a) Turn ignition “ON” to verify module LED is
flashing, otherwise test fuse slot for power and/or check crimp integrity,

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. 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.). This may not be an issue with optional
push button with built-in mic.
