switzerlandflagYes, believe it or not, in Switzerland it is actually illegal to use a GPS that has preloaded POI’s (Point of interest in Garmin terminology) or PND (or what ever they call it on your GPS unit) that warn about speed control cameras and police checkpoints etc.  If you are stopped and found using such a device it will be confiscated and you will be fined.

As from what I can tell it is only illegal if the device has loaded POI/PND for Switzerland speed camera’s/police checkpoints, the use of POI/PND for sights/hotels etc in Switzerland are still legal.  But mind you I got this from documents in German (not available in English) and my German is not all that good, so if you are passing Switzerland maybe you had better check yourself.
