Fastest speed on GPS

[sawman]

I was scrolling through different screens on my garmin the other week and came across this. Now I can assure you that none of my cars can achieve the max speed quoted, can any one explain how this would have been recorded!

Did you buy your Garmin from a PH member called 'dxb335d'?

I'm not sure that even a remapped 335d could break the sound barrier

Has your GPS ever been in a fast jet?

Well, Its been on a few transatlantic crossings but I don't think airbuses make that kind of speed do they? - anyway if it wasn't on it wouldn't log a speed would it?

Its because the software is st - you've had a poor signal/lack of lock onto the satellites which has given a false reading....this can lead to the position "jumping" - good software realises this is an error and disregards it

Though more likely to be this...

That sounds plausible, cheers
