Thread: WinCE iGO 8.3.5 settings not saved?!?

Been using the WinCE iGO 8.3.5 for a good few weeks now and realise the "sound" settings are not stored , as soon as the car is switched off, and back on again, I would lose the setting, and have to re-program it in...
Below is my sys.txt, am I missing some commands anywhere?
Or could any of you guys upload your sys.txt and let me compare what I have missing?
