A Bluetooth-enabled radio is now available as an option for Western Star's full product line, including the Western Star 4700, 4800, 4900 and 6900 truck models.

Mounted in the cab's overhead console, the Bluetooth technology enables drivers to talk on cell phones hands-free. Operating through the cab speaker system, the technology mutes the radio when the driver places or receives a call, helping drivers keep their eyes on the road and stay in compliance with hands-free cell phone laws.

Navigation systems with Bluetooth capability will also work with this new system. Similar to the phone, the radio is muted when the navigation system announces a driver's next turn.

The new Bluetooth-enabled system comes standard with Sirius XM Radio.
