RE: Re: [OT] TomTom+GPS ?

I seem to recall that speedos always err on the side of caution ie. they
read higher than the actual speed you are doing. I think it was something
to
do with car manufacturers not wanting to be held responsible for people
speeding if a speedo was reading lower than the real speed. Could be an
urban myth though;)

Marcus,

I get something like this every now and then but not so severe. The
indicator shows that I'm sideways in the road sometimes but corrects
itself as soon as you start moving.

The odd thing I have noticed is that my speed on TomTom is
constantly 4 mph slower than that shown on the car speedo.

using my Dell Axim X5 (400mhz) and TomTom 2.2.4 with a Rikaline 6010
SirfII GPS mouse. I've been pretty impressed with it in general but
one thing that is really bugging me know is that when the car is
stopped (i.e. standing traffic on the M60 every morning!) and I
start off the GPS resets it compass heading to 0 degrees (North) for
a second before calculating the true direction. The effect of this
is that the on screen car/map suddenly swing around for a second.
This can be very disorientating especially if just setting off from
a roundabout or junction. I understand that GPS units can only
calculate their orientation by reference to their previous location
but fail to see why it should reset to North every time. Apart from
this problem the Rikaline seems pretty good on sensitivity as I
regularly see between 8 and 10 satellites
