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 AUX device. In addition, a USB “Fast charging” 
port is included to keep devices charged while on the road. A push button with 
built-in microphone conveniently installed on the dash is used to launch Voice 
recognition applications (Siri, Google Now, Assistant etc.), initiate/end phone 
calls, launch applications and more.   

Note:  This kit works in C5 without 12-disc changer (or if changer 
malfunctions) Vehicles with functional 12-disc changers (or to retain CD 
changer playback); purchase our 

C5CD-HF

 or 

A2DIY-C5CD

 instead.
