I have tried serval version of iGO apps. The location on the map is accurate. the GPS signal seems pretty good, but iGO keep searching for GPS signals, can not start navigation. If I turn on airplane mode once then turn off, iGO then can navigate after that.
Does anyone know how to fix this problem?
Thanks for all replys. I have made three changes. let's see if the problem solved
1. add following lines in sys.txt
[GPS]
default_latitude = xx.yyyyyy
default_longitude = xx.yyyyyy
2. add following line in gps.conf
NTP_SERVER=us.pool.ntp.org
3. install smart time sync app.
EDIT:
Finally solved the problem with following statements in sys.txt
[gps]
location_net=0;1
location_gps=1
background_navigation=1
default_latitude=38.897211
default_longitude= -77.039972
