Introduction:
Safety comes first when you’re on the road, so having an intuitive and easy to
use Bluetooth kit is essential to reducing driver distraction. The C5-HF kit is
compatible with virtually all Bluetooth phones, and sounds great for mobile
conversations, streaming music or listening to AUX device. In addition, a USB
charging port is included to charge your device. One button with built-in
microphone conveniently installed on the dash is used to launch Voice
Recognition application (Siri, Google Now, Assistant etc.), initiate phone calls,
launch applications and more. Thanks to the C5-HF Kit you keep factory radio,
CD changer while enjoying Bluetooth features only available on newer cars.
Note: This kit is optimized for C5 without optional 12-disc changer. If
vehicle has a working 12-Disc changer, purchase our C5CD-HF instead.
See Frequently Asked question at the end of this guide for more details.

5. Connect or Tap red wire to ACC (Accessory) supply power in your

In 1997-03, locate 3-pin plug under passenger toe board near BCM
(may be covered with black duct tape) --- this plug has an orange,
yellow and black wire. Tap the yellow Accessory wire. (See Fig. 7)

7. Consider install location for control/mic button. Control button must
be within reach and facing driver for voice commands and phone dialog
(cable is 6ft. long). We recommend completing the rest of the
install prior to securing the control/mic button to the dash. To
install simply remove tape backing and secure to surface
Mic/control button custom installed next to traction control button
Ensure no ventilation duct is pointed towards the mic.
It is best to mount button facing driver
