Food for thought:

If radar detectors are illegal in Switzerland, how does Radio Zürisee
get away with publishing mobile radar locations reported from listeners?

Radio FM1 who broadcasts between St Gallen and Sargans was forced
to stop broadcasting radar positions. BAKOM (Bundesamt für Kommuni-
kation/the government) forced them to stop about six months ago. Now
they offer a SMS service which costs an arm and a leg.

What is the difference between Radio Zürisee and this iPhone App?

BTW, I know, first hand, that radar detectors are not allowed... for a
long time now
