The Cobra 29 LTD BT Blueooth is a unique CB radio that incorporates Bluetooth technology. This is the first CB radio in history to include this ground breaking technology. Drivers can activate the Bluetooth on the mobile phone and connect it to the 29 LTD BT Bluetooth to have hands-free calling through the CB radio. It is activated by a button on the microphone itself. If that wasn't enough, Cobra also gave the 29 LTD BT talkback and a blue channel display for a modern look.
