The GPSLockbox PTT cradle kit features a custom-fit, drop-in-and-out charging cradle with a cooling fan that helps to keep your device running when in hot temperatures. A sturdy metal mounting post keeps the unit securely in place. The powerful 20-watt PTT amplifier with on/off switch and volume control allows for simple eyes-on-the-road operation, even when wearing gloves. The noise-cancelling palm microphone has familiar push-button functionality. The smart 2.4-amp wiring harness can be wired with ignition-sense to charge up to 90 minutes after the vehicle has been shut off, adding extra charge and preserving battery life. An industry leading three-year warranty with advance replacement tops off this high-performance system.
