This detector picks up signals from all U.S. radar and laser bands, so that the digital voice alert will let you know if anything is happening anywhere around you. The STi Driver also offers 360 degree multi-sensor radar and laser detection, which means that you are covered on all sides, and will not be surprised by red lights or speed traps. The Digital Signal Processing (DSP) of this radar detector ensures that it will not go off at false alarms like garage doors. The STi Driver comes with the SmartPlug lighter adapter. The Beltronics STi Driver comes with a one year limited warranty.
