The installation of the Parrot was easy after getting the optional cable for a '09 Charger.  It's great how it uses the car stereo even with the stereo turned off.  When a call comes in it mutes the music then uses the volume set by the Parrot, not the volume the music was set to.  This bluetooth and a Garmin GPS was way cheaper than the factor options for these simple two things (gps/bluetooth option is over $2k while it costs under $400 to add these yourself. Can you say RIPOFF!).
