I like using navigation on my way to work/home just for ETA but don't want to hear the turn-by-turn directions all of the time. I know where the setting is to mute guidance but for some reason every time I turn it off it reverts back to being on the next time I get in the truck. I know I can go into the route options and mute the guidance every time, but I'd much prefer unmuting guidance when I actually need it. Also, changing the guidance volume setting in the same menu also reverts to the default when I restart the truck. Does anyone have any ideas on how to get the settings to save? Has anyone else experienced this?
