Introduction: Just because you drive an older car does not mean you have to settle for old technology. Many C5 owners will be pleased to know that they can upgrade the audio system to support Bluetooth Audio Streaming without replacing the Radio. The BLU-C5 connects directly to Radio OR if car is wired for CD Changer (10-pin); connection can be made there. CD Changer (if present) must be disconnected). A Bluetooth wireless connection means no wires, clutter or complicated setup. Pair Smartphone or Tablet and enjoy GPS prompts, Music Apps etc. on the car system. See Frequently Asked question at the end of this guide. Installation 1: (To Radio) Remove Radio from dashboard to gain access to the connectors.

Please click video link for help removing radio: https://www.youtube.com/watch?v=wtbwynjtsds 6. Bluetooth connection is temporarily lost when turn signal or wipers are turned on. What can I do to fix this? This is likely due to a power supply issue in your car and unlikely a bad module. If module plays continuously when wipers or turn signal is off, the module is fine. If Bluetooth playback is interrupted due to use of an accessory (e.g. wiper motors etc.) because these are loading down the circuit to which the module accessory wire is connected. If this occurs, consider relocating the accessory wire (RED) to an alternate ACC power supply location or have vehicles electrical system checked by qualified technician.
