Issue with planning routes in TomTom Rider V2

[ChrisJackson]

I recently bought a Tom Tom rider and have been planning routes on Tyre then loading them onto the GPS.

I followed one of the routes the other day and it was sending me on U-turns between the way points for no reason. Has anyone else experienced a similar issue or can offer a possible reason?

I understand that the Tom tom sees the way points and chooses its own route between them but this doesn't explain the random U-turns as there is no logic to this.

Another point is that when I returned home I simulated the route on the GPS and the U-turns were not appearing....

A possibility is that one or more off the way-points was sufficiently off the route to not be flagged as visited. Your TomTom insists on visiting every way-point along a route and was demanding that you turn back and do it's bidding...

As the mapping us in TYRE is Google Mapping data this can vary from the mapping supplied from TomTom so there can be discrepancies, though usually minor, on where the course of a road actually lies. Where this difference is greater than the proximity tolerance for flagging a way-point visited you can get this error.

This could be made even worse, or reduced, by any discrepancy between the TomTom mapping on your GPS and the real road. Maybe even by what side of the road you're riding on... Possibly explains why there wasn't a problem in simulation mode?

I had this riding through a village in Cheshire on the way to/from Wales for a weekend away. Outbound it was OK, but on the way back the waypoint was sufficiently off the road to make the TT navigate a loop around the backstreets Luckily I could see what it was doing and just stopped and skipped the waypoint.

Yep, stopping and manually marking a way-point as visited does the trick.

Dare I say that Garmin reduces the possibility of this happening as you use the same mapping to plan trips on your PC as is on the GPS. Additionally, with route shaping nodes you only get asked to turn back a couple of times before they get automatically ignored... I'll shut up now

Thanks for the replies so far. Unfortunately it seems to be a more complex issue, as the sat nav was taking me to a waypoint, then turning us back 15 miles to go towards a previous waypoint!! I'm wondering if maybe the route somehow got corrupted when transferring to the TomTom?

(Although when simulating the route on the device back at home it went the correct way?!)

I can't recall the file structure on TomToms but you should be able to find the ITN file and then open this in ITN Converter or TYRE to see if there's an issue.

Hi,

I have checked the file from the TomTom in Tyre and it looks fine!

Well,yeah, but no, but erm......

In all honesty it's only happened once somewhere in Cheshire on the way to North Wales and only in one direction.

The rest of the time I'm quite happy to live with TT's more logical routing and user friendly interface

If youload this script onto TomTom it will enable you to mark a missed waypoint as visited instead of going through the umpteen menu options trying to do same.

If you miss a waypoint and dont mark it off the tom tom will always route you back to it.

The script puts a arrow signon the tom tom map so if you miss the waypoint just press and hey presto waypoint marked as read. The beauty of it is that can do very easily.

If you use tyre zoom in on every waypoint to ensure that it is on the road you travel down and not just slightly off up a side turning. That will produce a miss when using the route however slight it is.

Hope this helps
