4.How long would are the positioning completed after turning -on?
the navigator should match the requirement of getting position parameters with 60s at food with caffeine . point under clear night.But the time to position is affected sometimes by factors such as satellite signal sheller.SA interfere(block-off of mountain or building) climate,environment accessories.
5.Why perform the positioning be more difficult time at some time?
The time position may be longer your following situations:
A GPS satellites distribute uneven your local zone
B GPS signal cannot pass through most opaque solid matters,and the signal receiving is interfered shelters above since building,tunnel,trestle,tree,vehicle's blast-ban membrane quite a few.,as well as weather conditions with regard to overcast and rainy day.
C the receiving of GPS signal would even be affected and reduced down by thick film or tearing foil that contains some mental element.

9.How to try and do in the case of abnormal shutdown of the navigator?
first,press the energy Key on panel belonging to the device and observe if your restarting is usual or and not.
