Tom Tom and actual speed
Has anybody else noticed how the actual speed on GPS is approx 5mph lower than the car speedo (especially at Motorway speeds).
Not just the Impreza, but every car I've tried Tom Tom in (and that's quite a few).
This can't be the speedo inaccuracy can it
Cheers,
Charlie

Car speedos are allowed to over-read by 10% (i.e. they can show you as going 10% faster than you actually are), but cannot under-read at all.
It would therefore be logical for car manufacturers to aim for a 5% over-read.
Or 5mph at 100mph

Yep its scary.... Tom Tom is more accurate than a £20k car! lol
One thing that is worth trying..... I have seen my brother do this on a video.
Next time your going on your hols on a plane. Take your Tom Tom and switch it on during the flight........ VERY VERY funny!
I'll not ruin the suprise...... but if you do want to know the result, PM me

You have to have a gps device connected to the tomtom device in order for it to work,only way is either a gps bluetooth receiver or a cable gps receiver without either of these the tomtom cant get a signal from the satellites surely?

My PDA one doesnt,it comes with the software and a cable gps receiver.I guess the tomtom in question is like one of the tomtom Go systems? never had one of those which is why i was interested in how it works on a plane.Also why would anyone take a tomtom on a plane?

Tom Tom or any other Sat nav still needs a line of site to two or more satellites, still would imagine it difficult to work even remotely on a plane unless you're holding it upto the window.
Off course it'd be ok I guess in the Window of something like a Cessna, apart from the fact it'd have a bit of a fit as far as altitude and relating it's position to the in built maps I guess.

Ive had that many PM's I'll just post the result here. Sorry if its going to ruin the suprise, if you fancied trying it out.
Well you know the volume gets louder the faster you go...... imagine nearly 500mph! everyone on the plane heard!
But because the route kept changing off the roads (cross country) he couldnt switch it off because it was trying to re-calculate the route.
He did eventually get the mute working and videoed the map moving accross Sussex travelling at over 500mph, then it got very confused over the English channel.
