tbourner Posted May 10, 2005 Share Posted May 10, 2005 Is there such a thing as a GPS speedo? I don't really feel the need to get a speed trap detector or anything as I generally stay within the limit and there aren't many cameras around here anyway. But I'd like to know exactly how fast I'm going on the motorway and stuff, especially since I have the km-mph conversion, as well as getting new bigger wheels and tyres, and obviously tyre wear affects it etc. etc. Are there any reasonably priced GPS speedos out there?

Jake Posted May 10, 2005 Share Posted May 10, 2005 Just calibrate your stock speedo with a GPS and a Thor DSC. Job done. No need to carry a GPS once you've done it. Mine is spot on at any speed over 30mph. Link to comment Share on other sites More sharing options...
michael Posted May 10, 2005 Share Posted May 10, 2005 In my experience the GPS is only accurate when you are at crusing speed, mine can't keep up under fairly hard acceleration or braking but gives a better idea once you behave yourself Link to comment Share on other sites More sharing options...
Jake Posted May 10, 2005 Share Posted May 10, 2005 I agree. And that's another good reason for calibrating your speedo against a GPS. Link to comment Share on other sites More sharing options...
tbourner Posted May 10, 2005 Author Share Posted May 10, 2005 What's a DSC and what does it do? Link to comment Share on other sites More sharing options...
tbourner Posted May 20, 2005 Author Share Posted May 20, 2005 So is the short answer no then? There is no such thing in the world as a dedicated GPS speedometer? Link to comment Share on other sites More sharing options...
michael Posted May 20, 2005 Share Posted May 20, 2005 http://www.gaffrigperformance.com/Products/gauges.cfm?theSubCategory=42 I'm sure there are more out there. Link to comment Share on other sites More sharing options...
