Radar detectors are an excellent way for people to avoid getting ticketed for speeding, now you can purchase radar detectors that are completely stealthy and look like any other car audio device. You no longer need to mount them on your dash, and they now come in different shapes and sizes that don't look like traditional radar detectors.
GPS technology has become more and more common, it has even been built into radar detectors. The best radar detector will have a stored database of things like stop-light cameras and common speed traps. These devices are also quite stealthy because they simply look like a standard GPS navigation device. Some radar detectors have built-in GPS navigation; it serves the dual function of giving you step-by-step directions to your destination, while also highlighting on the digitized map where radar activity may be located.
