Update, as published in our local rag, in time for the summer touring season.
Briefly, explained thus: Drivers that use specific radar detectors, such as the Coyote, maybe liable to being fined. GPS devices that are not radar detectors maybe in breach of the law if they give specific warnings of radar. It seems that if the warning does not mention Radar, but something more general, such as danger areas that include other dangers, then apparently it is OK. So if your unit has the word Radar as a warning then by updating the software to say Danger Area then it may get round the problem.
