Thread: Converting track logs to Garmin IMG maps?

I've encountered a strange issue I was working with a route that was shaped like a U. I tried routing on MapSource from from the beginning to the end point, but instead of following the U trail to it's completion, it worked for a bit then jumped across halfway. The jump was a few hundred meters. Why would it do this? I set the ROUTE_LVL to 1.

I have a few more mini questions that I probably know the answer to but I'd like to confirm it:

To connect my custom map routes to existing Garmin maps, they have to connect to them and not even be a pixel off? I thought I had my routes connected to main highways, but when viewed in MapSource a few were a pixel or two off and didn't route!

& Every "intersection" or "turn" in my route no matter how short has to be it's own line (and connect) or else routing will lead follow it even if it is in the wrong direction?

Can you make a shot? Or if possible attach the map.

I know it is hard. Maybe you can try by extending the route. Make it longer. Maybe this could help.

That is why most of the third parties maps can't be used together. Just their roads differentiate on the boarders.

The last sentence about the intersections and wrong directions I couldn't understand. Sorry.
