External power removed no more GPS with Igo primo 9.2.0.192885 on Chinese Gps window 6.0
When the car power is disconnected the Gps says ”external power removed” the timer come saying the unit will be turn off after 10 seconds but when it turn it back on, the Gps come back right away, the screen say Gps has been turn off. I try to click “turn on Gps” but this do nothing until I completely turn the unit off and back again any idea?

The unit is not really turning off, it's going into Sleep Mode. Some devices have a hard time waking back up from sleep mode...they lose connection to some hardware, lose the ability to fully access the SD Card, etc.
In your case, if it's a hardware thing, there may be nothing you can do about it except to maybe exit Primo before the power is disconnected. Then, if it goes into sleep mode and wakes back up when the power is back on, start Primo and see if everything works OK. It's an extra step, but it might be necessary with your device and how it is set up.

Try to put the following command into sys.txt file, it's in the path: igo8/ or in Primo/ .
