Just when you think things couldn't get any more gloomy in the world of in-car navigation systems, here comes news that high frequency processors surrounding your GPS system could actually cause some seriously screwy routing. According to a study by the Swedish Defense Research Agency, "computers used near a NAV could disturb the signals utilized in the GPS receiver." More specifically, Intel CPUs with clock speeds of 1.7GHz, 3.0GHz, and 3.2GHz were pinpointed as potential troublemakers, but a member of the study actually went so far as to suggest that a variety of other (untested) chips could indeed wreak the same havoc. The study showed that "modern computers produce interfering signals that reach as far as the frequency bandwidths used for GPS systems," and while specific reactions weren't apparent, testers did suggest to move any computer equipment further away from the GPS unit if it began to "play up" for no ostensible reason. Of course, we've huddled our own laptops and GPS systems together on many occasions with no ill consequences, so as always, your miles may vary.
