B.The weather is bad
C.Too many shelters(tall buidings,vehicle’s blast-ban membranes,tunnels,viaducts,trees ect.)
D.There are other wireless transmission enquipments.
E. Car explosion-proof membranes and the screen whith high temperature
2.What can I do as the map is lost during formatting?
There are map data backup in the CD-ROM.You should unzip the data of the folder “GPS map” in the CD-ROM in the SD card.After inserting the card into the GPS navigator and turning in on,the system demands activation code,Then input the right one (call your dealer for it) according to the hints to reactive the navigation system.
3.Why the stand-by time of the navigation instrument is too short sometimes?
A :The duration of the lithium battery varies with environmental temperature changes and the service conditions.If the environment temperature is too low or too high,the duration of the battery will be affected.It is recommended to use this device at the room temperature.
B:When the device is being used ,larger screen of the navigation device requires more electricity.In addition,affected by the volume increase,sound field special effects,and other factors such as frequent operation,the actual duration may be different from specified one to a certain extent.When the device is used in the car,it is recommended to connect the car charger and charge the device while using it.
4.How long would be the positioning completed after turning -on?
the navigator should meet the requirement of getting position parameters with 60s at the same point under clear sky.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 etc.
5.Why do the positioning take longer time sometime?
The time to position may be longer in the following situations:
A GPS satellites distribute uneven over the local zone
B GPS signal can not pass through most opaque solid matters,and the signal receiving is interfered shelters above such as building,tunnel,trestle,tree,vehicle’s blast-ban membrane etc.,as well as weather conditions such as overcast and rainy day.
C the receiving of GPS signal would also be affected and reduced down by thick film or tearing foil that contains some mental element.
6.Is it free to receiving GPS satellite signal with the navigator?
Yes,the receiving of GPS signal is free of any charge.

Incompatibility may occur,because there are different compilation-modes and resolutions for the files of same format at current websites.All you have to do is convert their format using recommended conversation tool attached to disk before playing them.
8.How about the precision of the navigator?
The precision of the GPS,which comes from the statellite position technique of the USA army,is completely in the influence of the precision of USA’s GPS satellite signal.According to the offical data,the precision is whithin 10 meters;and commonly ,it may be more precise in 6 meters at more than 90% time.
9.How to do in the case of abnormal shutdown of the navigator?
first,press the POWER Key on the panel of the device and observe if the restarting is normal or not.
Then,check your power supply cable fuse,change it if it is broken.
