Thread: iGO primo keep searching GPS signal after loss signal even there are 8 or more signals in use.

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

location_gps=1
