Gerd,

don't think so, but not completely sure:

If this happens I think to remember that it shows 'in the middle' (map center) my actual position... but how I got there isn't properly visible anymore as the track just shows a straigt line, guessing from my last position where I actively used the GPS.

Hi Patrik,

I also see this from time to time, but I think it happens only when I touch
the display so that the device switches into a different mode. I don't know
how Garmin calls it, I call it move mode. In this mode the device shows a small
arrow in the bottom left corner, and it is no longer changing the map center
to my position. Could this be your case?

Subject: Re: [mkgmap-dev] Track rendering on device

I have from time to time an issue on my 450t that might belongs into the same category.... 'unfortunately' also with mkgmap created maps (fzk) as I normally don't use the official garmin ones:

If I look at the garmin after a while in action (moving) it happens from time to time that the displayed recorded track (my actual movment) diplays wrong. It does not display my real movement but just has a straight line from somewhere off the map to the actual position.... as soon as the display get's updated (because it's turning due to my movment) or I zoom in/out it's displayed correctly again...

Actually I've noticed this only on the 450t not on any other garmins I use with the same maps (eTrex 30, Monterra).... if I remember correctly.

Not sure if it's the same, a similare or a complete other issue....

Cheers

Patrik

Betreff: [mkgmap-dev] Track rendering on device

Hi all,

I wonder if this is a problem that is specific for maps generated with
mkgmap :
When I chose a track as target for routing the track is displayed as a
magenta line. When I follow this track on my bicycle the device sometimes
fails to render the map, as a result large areas are flooded with magenta .
The device is an Oregon 450t.
The problem disappears when I move a few meters or chose a different zoom
level. I'm never able to reproduce the problem at home, so I guess
it is related to the movement, maybe combined with low batteries.
I did not yet try if the latest changes regarding MapSplitter improved
this.
Did anybody else see this effect in original Garmin maps?
Any idea what the reason is?

Gerd
