Will my Avoid and Prefer segments be retained when upgrading to Guide 19?
Last Updated: January 03, 2018
The update program will make a best effort to retain your previous avoid and preferred segments from the original installation. However, due to significant highway, junction, and road segment changes, not all avoided or preferred segments may not be able to converted to the new version. The update program will log such segments that could not be kept after the Guide 19 update is completed.
