Introduction 

Many C5 owners will be pleased to know they can upgrade their audio system to

OR if vehicle is wired with 10-pin plug for optional 

12-disc CD Changer in hatch or trunk; connection can be made there

. If vehicle 

has a 12-disc CD Changer, 

it must be disconnected or

no wires, clutter or complicated setup. Pair Smartphone or Tablet and enjoy 
navigation, internet music sites, audio books and more on the car system. This
