This system is great for longer endurance races and comes complete with a Motorola Digital CM300D mobile radio. The radio is hard-wired to the battery of the car, so there are no batteries to worry about! System includes a custom, in-house built car harness with a steering wheel ‘Push to Talk’ (PTT) and connection for the helmet kit. Also included is an external antenna kit that will increase the range of reception. A driver’s helmet kit and ear pieces will complete the car package. For your crew, we have another Motorola Digital CP200D portable and our Racing Radios Classic headset with noise cancelling microphone. This is a complete system and is ready to be shipped out.
