Built-in breathalyzers haven"t become quite the mainstay that many other features have in GPS units, but it looks like they"re starting to become a bit more common, with AVMap only the latest to debut a navigator that promises to tell you if you"re fit to drive or not. Apparently, its new Geosat 6 Drive Safe navigator is a standalone version of the built-in option that was available on Peugot"s 107 "Sweet Years" edition car, with it boasting the same 4.8-inch touchscreen, built-in Bluetooth, and text-to-speech features as before. No word on a price just yet, unfortunately, and it seems safe to assume that this one will only be available in Europe.
