Speed detection problems on Garmin StreetPilot 2730

As I was driving near Springfield, Illinois... My Garmin told me I was doing 43 miles per hour for a few miles when I was clearly doing 74. I set the cruise control based upon the GPS 71 MPH. (GPS 71mph = Speedo 74 on this trip, in this car).

So, why was it that the Garmin freaked out and said I was doing only 43 MPH for a time? Is this common? Is it fortelling of other issues? Or is something I should just get over?

(FWIW, I was in Southern Illinois, in the middle of nowhere... no tunnels, overpasses, excessive trees, etc. There are no hills in Southern Illinois)

Thanks,
Tim

Speed detection problems on Garmin StreetPilot 2730

I also have a 2730 and have not ever experienced the problem you described.

My MPH on my 2730 has always been within a couple of MPH of my car speedometer.

Sorry I'm not any help.

.

I would regard it as a glitch but at the same time, be aware of anything similar and if it happens with any regular frequency and/or location.
