Trip Repair Tool

What problem does this tool solve?

When deviating from a route the zūmo XT will try to get you back to the point where you deviated from the route, even when recalculating to the next route-point would be faster. It will do this until you are about a mile from the original route. Often the zūmo XT will insist on making U-Turns. Hence the abbreviation RUT, that stands for Repeated U-Turns.

Most people consider Repeated U-Turns a problem, and would prefer recalculating to the next route-point, if that's faster.
If you disable U-turns, the zūmo XT's behaviour will change slightly, but it will still not aim for the next route point.

Background information

Multiple tests carried out, reveal that when a trip is created on the zūmo XT itself, it will recalculate to the next Route point. If a trip is imported from an external planner, like BaseCamp or MyRoute app, it will demand U-Turns. You can check this by opening the Trip planner, trips will either be listed under "Saved Trips", or under "Imported Trips".

What does this tool do to solve the problem?

All trips in the trip planner are stored in Internal storage/.System/Trips as nnnnnnnn.trip files. In these files there is a flag called "mImported" that defines whether a file is listed under "Saved" or under "Imported". Modifying this flag by setting the value to "00", will result in the file being listed under "Saved". And not only is it listed under "Saved" it will also behave like a Saved trip. That is, it will not direct you to make U-Turns, but it will recalculate to the next route-point. Of course if a U-turn would be faster it will demand for a U-turn.

How do I use it?

Make the .System folder visible. More info can be found here.
Copy the trip files to the hard-drive of your computer.
Click on "Upload trip file" below, and select the trip file.
The program will display file name, trip name and if the file was modified.
Click on "Download Trip File", only if the file was modified, and save it on your hard drive. The trip file will be named <original_name>_mod.trip. You can change the name to something meaningful.
Copy all modified trip files back to the zūmo XT to the original location.

Notes

Mac users, read this for more info on how to access the file on the zūmo XT.
Some browsers and platforms support downloading and maybe uploading directly from/to the zūmo XT. If your system does support this, manually copying the files is not necessary.
Take care not to have multiple .trip files on the zūmo XT with the same trip name. For example if you're modifying file 12345678.trip and copy the resulting file 12345678_mod.trip to the zūmo XT without deleting the original, the trip will be listed twice. It will be confusing.
