Now you can add an optional heads up display to Kenwood's D-Mask and D-MASK + head units. This is a compact box with a transparent screen that sits on your dashboard. It will show you the basic head unit functions such as the radio station frequency CD track number. Or by adding optional sensors you can display temperatures, inside and out, battery voltage at the battery and at the amp, and it will calculate the difference. You can also connect Kenwood's optional Weather Band Tuner to a compatible unit and you will have a weather band radio. Since there are more than 480 weather broadcasters across the U.S., you'll be able to get the latest forecast instantly.
