Satelite reception lost constantly
In order to receive satellite signals your GPS receiver must have a clear view of the sky. If you are using the GPS inside of a vehicle the body of the vehicle may shield the unit from receiving these signals.
To minimize this the GPS should be mounted at the lowest place within the automobile that has a clear view of the windshield and side windows. If you continue to have problems then you might consider purchasing an external antenna for use with the GPS.
Even with a properly mounted GPS you may occasionally lose satellite reception due to local terrain (hills, mountains, dense forest etc.) or other obstructions (parking garages, tunnels, etc.) which can block reception.
