Yes—the 2007 Chrysler 300 has Bluetooth, which was one of the first years that the Chrysler 300 had this feature. The only unfortunate downside of this particular Bluetooth system is that it’s only for voice recognition and hands-free calling. You cannot stream music via Bluetooth on a 2007 Chrysler 300.
However, you can always use other gadgets to stream music from your phone. You can plug in a1/8 inch-thick audio jack from the auxiliary port into your phone to play music. Alternatively, you can use an FM modulation Bluetooth car kit, which will allow you to use an FM frequency to play music on the Chrysler 300 audio system via your phone.
