    Question FD Problems... runtime error, speed miscalculation and maps!

    Hi There,

    FD is great - unlike most other apps I've tried, this worked first time. However, I have got a couple of problems:

    1) I installed FD v0.80 which worked first time, but got a run time error (9 - subscript out of range) when selecting the DefaultTouch skin. I downloaded v0.85 Freedrive.exe file and overwrote the v0.80 file but this still doesn't work. If I then restart FD, I end up with a screen with a grey border and no UI. Is this a known bug?

    2) On a recent test drive I noticed that the speed indicator was consistently 5-6mph lower than the actual speed. Is there a facility to compensate the GPS derived speed - this will obviously be important for the speed camera notifications! I appreciate this is not a problem with FD but it would be a useful feature.

    3) I recently purchased what I believed to be the latest edition of D3 - unfortunatley it turned out to be Q2 2003 rather than the Q4 2004 maps that I was expecting. Is there any source for obtaining maps on their own - even just the UK maps would be a good start.

    4) I assume that once I obtain and update the maps to the latest version I will start to get more meaningful instructions at roundabouts? At the moment the instructions I get do not tell me which exit to take.

    Keep up the great work - I've been following these forums for a long time and have always been impressed by the wealth of information available.

    Many thanks,

    Paul.

    I think you'll find the GPS is probably more accurate than your speedometer. The manufacturers set them high by a smidgin

    Still not convinced!

    I was travelling at (what my speedo indicated was) 75mph past a speed camera - FreeDrive reported 81mph and rightly alerted me to the 70mph limit. Had I actually been travelling at 81mph, the camera (which I know is active) should have triggered. I was travelling at a constant rate on a flat road. It does seem odd - this would indicate that my car speedometer is reporting a slower speed than the genuine speed. Given the 6mph difference, I would expect to trigger speed cameras regularly - as such I am more convinced that it is the calculations performed by FreeDrive/Destinator or a problem with the GPS device itself. I will try another product to see if that gives similar speed differences.

    Thanks

    Paul.

    speedos in peoples cars are 10% out..

    30mph on speed = 27mph
    40mph = 36mph
    70 = 63mph

    my gps and speedo are on-par with the speed displayed on the radar-operated "your speed is" displays.. but on every other car i've had until now the speedometer showed ~5 mph faster than I was actually travelling.

    understandably, it is better to "err on the side of caution"
