Thread: IGO Nextgen Israel loses signal GPS while driving

I do not know why people think by having "show_glonass" in sys.txt it will help with GPS signal problem. That setting only show the status of GLONASS, nothing else.
As for the max 12 satellites status, you only need 4 to locked, to get 3D position. You should pay attention to the signal strength of those satellites. Use another proggy to monitor the signal strenth.
As for "Navitel holds fix GPS", different nav handled weak signal strength differently. If your unit handle weak signal strength poorly and the satellites go in and out of locking, NextGen might dropped and re-acquired. It could be a faulty GPS chip (I have a phone that does just that)
