According to the owners manual two BT devices can be registered at one time.

This is a nice feature since my wife and I both have iPhones.

The BT feature also allows music streaming from each device (iPod/iPhone music library) and playing thru' the audio system from either device, below is some info from the owners manual:


The Bluetooth® audio system enables you to enjoy music played on a portable digital audio player (portable player) from the vehicle speakers via
wireless communication.
This audio system supports Bluetooth®, a wireless data system capable of
playing portable audio music without cables. If your portable player does
not support Bluetooth®, the Bluetooth® audio system will not function.
Vehicles with a navigation system:
Refer to the “Navigation System Owner’s Manual”.

Vehicles without a navigation system:

While I haven't tried pairing two devices at once, I will say that it was simple to set up audio streaming from my iPhone to the head unit. I can now play Pandora all day long.

Someone (either here or somewhere else) said that it didn't work. I was pleasantly surprised that it does.

Even better, if it can control thru steering wheel buttons for Pandora.
