Here should be what your looking for http://gpsinformation.net/ More specifically http://www.gpsinformation.org/perry/chipset_firmware/ And, as previously asked, are you sure there is a steady version progression?? Chris Tulloch

Legend HCx has an upcoming turn beep, and a turn emminent beep....They are able to be changed....default is single beep for upcoming, double for emminent...There are a few louder and more annoying tones there also... You can also turn them off individually....So, Check your settings.. Dark

No Matter what anyone thinks, cell phones, GPS units, Radios, talking to passengers...etc, All have the same effect...They take your attention from the road, and slow your reaction time.. I think any use of above should be treated in the same manner as Drunk Driving, since they are essentially the same thing... Dark.
