It releases up to ± 37 MB of RAM (see below) and I never have any satellite problems with my GO x20, x30, x40 x50 and 9000.



N. B. The On/Off button does not really turn off the GPS, it puts it in standby. As soon as you reconnect the GPS to the cigarette lighter, to the 220V mains or to the USB port of a computer, it wakes up immediately and picks up the satellites in ± 30 seconds, even indoors. To extinguish it effectively just press briefly "Reset". The restart must then be done by pressing the On button and lasts longer, but it finds the satellites very quickly.

I did not put the "LoquendoTTS" and "voices" folders, because they contain French voices.

P. S. To update the position of the satellites, double-click on the executable file "QuickGPSfix_SiRFStarIII.exe" (x20, x30 and 7000) or "QuickGPSfix_GlobalLocate.exe" (x40, x50 and 9000) which is in the "ephem" folder.
