Posted: Thu Jul 12, 2007 8:19 am Post subject: Erroneous Navigation Instructions
After updating my Mio with the latest maps, 3.2 software etc a little while ago, I was suddenly alerted by a voice saying "in 50 yards turn right".
This was despite:
a) travelling at 70ish down the motorway - so it would not have been safe to turn, even if I didn't have to cross the central reservation and the other carriageway
b) there was NO road on the right
c) the highlighted route was showing that I should continue down the motorway
d) I was at least half a mile from the nearest junction, bridge etc
e) when I ignored this instruction and continued along the motorway, there was NO "route re-calculation" message
I thought this was a little strange, but dismissed it as a one-off glitch.
However, this error has occurred again in the same location - although it doesn't happen every time I travel this route, which I use most days travelling home from work - M3 between junctions 4 and 4A, southbound/westbound (heading towards Basingstoke/Southampton).
Has anybody else noticed such intermittent, but reproducible, erroneous instructions?
I think that Retty is also a regular user of this route, so I'm hoping that soembody may be able to shed some light on this. _________________ Andy

So it can't be a built in routing error. It can happen if you temprorarily get down to only 2 or 3 sats. locked. TT will then lock on to nearest road, which could be parallel some distance away and TT is instructing you from the point it thinks you are. Next time it happens check where the blue position triangle is, probably not on the road you are travelling but to one side or the other.

As far as I can see, satellite reception is OK.
There are no trees, tall buildings, hills or anything else which could possibly interfere with reception and it's happened in different weather conditions too. _________________ Andy

That's a weird one then. I still believe it cant be a routing error or you would get it all the time.
Overhead power cables, athermic screen in your car?
Recently there were half a dozen new satellites put into service and I noticed the 'bars' on some hit the roof. Maybe it's happening if the sats. with the weaker signal are overhead.

Next time it happens just check to see where the position of the icon on screen is, it be off your route. I say this because in the Teign Valley I always found when I passed under some overhead power lines I lost reception and shortly after my position was shown as being in the adjacent river.

I don't think there are any overhead power lines in the area and I don't have a fancy windscreen.
I know roughly where it happens, so I'll keep an eye on things and see if I notice any anomolies if/when it happens again _________________ Andy
