Check the last received position for your GPS. If the last received position is not current:
1. Check that the GPS is flashing and is turned on.
2. Check that Show on map is switched on under "My dogs"
3. Check the signal strength from the last received position
The signal strength will not be updated if the GPS does not have contact with the GSM network and GPS satellites. The information is based on the last time your GPS sent in a position.
