The Rugged Radios Nitro Bee Xtreme can be integrated with a single-seat car harness and 2-way radio or 5-pin headset using this accessory cable. When configured with a single-seat car harness and 2-way radio, the driver can transmit and receive on a 2-way radio. When a Race Control call is received, the Nitro Bee Xtreme mutes 2-way radio audio, giving Race Control audio priority so the driver does not miss critical race communications. Compatible with Nitro Bee Xtreme only.
