Cobra Forges Ahead Again!!    Presenting the First Ever 40 Channel CB with Bluetooth® Wireless Technology!!

Incoming audio is routed through the radio's 5-Watt CB speaker and boasts a One Touch Bluetooth operation, so professional drivers now can communicate clearer and drive safer! The unit also boasts one-touch Bluetooth operation, so that drivers can stay focused on the road by answering and terminating calls with the push of one button. An auto-redial feature also allows for one-touch redialing of the last number called.

The new unit offers 4 Watts AM RF power output, the maximum amount of power allowed by law; Talk Back controls allowing drivers to adjust the desired amount of modulation talk back; a Blue Channel indicator displaying channel selection in cool blue illumination; and Delta Tune which is used to clarify incoming signals.

The Cobra 29 LTD BT transceiver is one of the most advanced AM two-way radios used as a Class D station in the Citizens Radio Service.  This unit features advanced Phase Lock Loop (PLL) circuitry providing complete coverage of all 40 CB channels.
