Jumping off the road

2011-01-19, 15:13 PM

I've had a couple instances with my new tn565t where when driving the GPS car position "jumps" some distance off the road (maybe 10-50 yards) and stays there until the power is cycled (shut car off, then when back on seems to be normal).

I haven't been on long trips (I was back home and powered off within 5 mins of this happening both times) so I don't know if this is something that would correct itself without the power-off. It is a little disconcerting that this happens -- not sure how it could happen without there being some bug in the GPS itself?

I did update to the latest available OS and maps as of last week.

Any suggestions appreciated, thanks!

  Out of curiousity, when this happens, how is your satellite lock status at that time? Are there fewer then 3 or 4?

I don't recall seeing the "Searching" message pop when this happens. I haven't checked the GPS details when this happens so I can't answer that, sorry. I was on normal suburban roads both times, although if it matters to sat lock it may have been pretty cloudy (northeast OH snowbelt area).

If it happens again I will try to check the # of sats being used.

BTW, I've had a TomTom One SE (a 3.5" low-end model when purchased) for 4 years. It's never happened with that unit in the same area.

  Yes, if possible, see how your signal status is when your unit acts up on, that may help determine what is happening, thanks.......

If it helps, I also saw some inaccuracy in my actual position the first time I took my TN765 out on a run.

It would show me some distance off the road but parallel with it!

After a while it stopped doing that and has been super-accurate ever since.

If it doesn't quickly 'bed-in' and start behaving like you'd expect, a soft reset might help.

Your old TT maps may have more accurate data than the Navteq maps in the Moto. Hard to believe, but possible.  In my estimation Moto took the cheap road with regard to level of map data, POIs, etc. they purchased from Navteq.     All automotive gps' on the market use a "rubberband" technique to keep your vehicle icon on the known traveled roadway since they aren't as accurate in determining your position as many think, even with SA turned off years ago.

The signal loss, as mentioned, may well be the culprit at that moment in time.  If a soft reset does not help and you are not vested too deeply in lots of Favorites or saved routes then a hard reset may be worth a try at some point.
