MT-1 location gets lost

josep vicente5 years ago

Dear all,

I recently installed an MT-1 (identic to sinotrack ST-901) in my bike and i realized that after parking, the GPS wakes up and goes back to a previous location.
For instance, i arrive home from work at 6PM. 3-4 hours later the GPS sends the location from the highway, where i was indeed in my way home.
I called the GPS and it sends me the SMS with this same location, but the bike is in fact in my garage.

Any idea on what could be happening?
