@Jonnyj @SunsetRunner Thanks for taking a break from stepping to visit the Community. @Jonnyj The GPS signal can be affected by numerous reasons, for example if are inside a building or a house. If your Surge is having a hard time to find signal during your activities you can use the "Quick Start" option. Additionally, it could be a good idea performing a restart to your Surge by following @Rich_Laue's steps. If none of this helps, please provide more information about the problem you are having to address your question better.
Catch you later.
