Hi,
Not sure why but my maps have a red line which does follow some routes i have completed but also shoots south across the world.

Does anyone know what this is and how to get rid of it?

Thanks

A stray waypoint?

It not a current journey, it seems to be a collection of previous journeys i've done but one of the lines just shoots half way across the world.

Afterthought

I've just noticed. Its not a red line - it is an orange line.

Orange is the default colour setting for a manually recorded track. If you start recording a track, it doesn't stop recording until you stop it yourself, and it is displayed on the screen as an orange line. Normally curvy. If (for whatever reason) the satnav thinks that it is in South Africa and the record track button is pressed, it then starts recording a track wherever it goes until the recorder is turned off. If the unit is turned off, then it contnues recording when it is turned on again.

So lets assume it was in South Africa somewhere when the recorder was started. The XT is then turned off and put in the mail. It gets sent to the UK, where it is turned on again. There are no recorded points, so the Zumo does what it always does - joins the last two points togther with a straight line - it's just that the last two points are normally a few metres apart, not a few thousand miles.

I am not suggesting that your unit has been to South Africa. But it thinks that it has. When first turned on the satnav doesn't know where it is and it has to work it out from satellite positions signals. But satellites move all the time and it doesn't know where they are until it knows where it is and what time it is. So as it finds signals from more and more satellites it is gradually able to make an estimate of its current location, and use that to find satellites to make a better estimate. But that can take it a few minutes. If during that time, the recorder is activated - the position will be miles out. It would be interesting to see the track log to see how fast it reckoned you were traveling on your journey from South Africa to the Uk in 3 minutes.

So to answer your question - the following items will help you to get rid of the orange track. They are not a sequence. Just separate items that you can turn on or off.

To Turn off the recorder: Main Screen -> Track ->Stop.

To Delete tracks recorded in this way: Main Screen -> Track -> Track Icon top left -> Spanner -> Delete and choose the tracks you want to delete.

To stop showing any track history that has been recorded automatically:
- Main Screen -> Settings -> Map & Vehicle -> Map Layers -> Travel History - untick. This will stop showing the automatically recorded travel history.

To disable recording of your rides, (which also removes the capability of the device to adapt its calculation of route times and ETA)
- Main Screen -> Settings -> Device -> Travel History

(Personally I like to keep these. I downoad them every so often and they are an extremely useful reminder of where I have been and when - especially when loaded into a mapping program. Basecamp can be used for this. I use MemoryMaps with Ordnance Survey maps of the UK.

You may be on to something there.

No sure why that was on but is worked...many thanks.

Think in trying to work it out i deleted all the roads i'd ridden on so when i'm riding around it wont show roads i've visited before.

But at least i dont have a big line heading to Africa

Oh good !

I'm please about that ! You may have spotted - I had 3 goes at answering that question. I've kept what I had written, but there is no point in cluttering up a thread with my previous wrong answers. It was useful information - but once I had realise what the real answer was - my other replies were irrelevant.

Glad it is sorted.

Nb if you want to keep your 'where I have been' tracks - you can get them from the Internal Storage / GPS folder. CurrentTrackLog.gpx. Older rides are all in the Archive folder. Don't delete them - just copy the contents of the folder and the Current Track Log.
Older tracks get wiped when they have been there about 6 months.

If you want to keep copying them, copy all of the files in Archive into the same place on your computer - let the computer over-write existing files. The reason is that the Zumo modifies the files after they have been archived - it does a bit of tidying up and joining together tracks from the same day so that they are not split acorss a number of files. So for example, when it has just written 10.gpx - 7.gpx, 8.gpx, 9.gpx may have been altered. You may even find that one of the numbered files has disappeared. It will have put its contents into other files. So just let it overwrite exisiting files with the same name - because the Zumo has the more upto date version. The new CurrentTrackLog can be allowed to overwrite the old one too.

I have mine recording the data all of the time, but the display of the data is turned off - unless I am going somewhere for the first time this year - eg a trip up to Scotland.

Possibly the same as I had recently

A good thought, but this issue is definitely a track. Your issue look similar but is definitely a route. I'm about to post some thoughts on your post, because I've just realised what it might be.
