Cube gps moves around about 100ft? Is that normal?

I dropped my vehicle off to be worked on and noticed it only updates once every 24hrs now and sometimes after it updates it will show its like 100ft in a different spot, but it doesn't show that it actually moved. I think they've moved it a couple times, but the rest of the time was just inaccuracy in the gps. You can check and see what time its been moved, but the fact that it updates everyday at the same time and now it shows its sitting 100ft in the woods is kind of annoying. Guess 100ft is about as accurate as it gets for a vehicle tracker?
