I don't know what setting changed, but for several weeks now, I haven't been able to get my navigation system to keep using the full screen. After a minute or so, it drops into a split-screen mode in which the right half is devoted to audio, which is incredibly stupid because all it is doing is wasting half the screen to tell me I have the audio off. It did not do this before. I can't find a setting to make the "home" screen full-screen NAV. I don't really care if the "home" screen is full screen NAV or 50/50 NAV/audio, but when I choose NAV I want it to keep using the full screen for NAV until I tell it to stop.
Do you use Entune? Could it be returning to the audio screen at some point? I also have a Four Touring; I don't use Entune. My map stays full screen until I change it.
On mine you just touch the tab on the split and it returns to full screen and remains there until I touch the tab again to re-open it.
On my 2016 Prius v Three the setting is in Apps > Setup > General... "Auto Change to Home Screen" either checked or not checked depending on what you want. I have mine not checked so the Nav display stays full screen once I tap on it.
OK, I'll look for that. (Later) Yeah, "Auto Change to Home Screen" was checked. I'm pretty sure neither my wife nor I changed it since, we didn't even know it was there. Thanks. I haven't had a chance to test it yet but I'm sure that's it. It's possible that the setting was somehow accidentally changed when the dealer had it in to apply the parking-assistance update.
Good...hope that was it. I normally keep my home screen in two panel mode, e.g. Weather and Nav. I use full screen Nav on long road trips.
Mostly we love our 2016 Prius, but the NAV is a sore spot. It sucks so badly I'd just go on using our little suction-cup Garmin except that there is literally no place to put it. The NAV has really been a disappointment, and, in particular, the quality of the database sucks. On our last trip, it said it knew where a specific KOA campground was, and it guided us into a suburban neighborhood and took us to the front of someone's house and said we "had arrived." The campground was actually five miles away. Looking for a restaurant in St. Cloud, MN, in a neighborhood with mostly fast food, it listed what it said was a restaurant named "Abda Salad," and we believed it, and it led us into an apartment complex with no restaurants of any kind. I was strongly tempted to go into the building just to confirm our guess that it was actually somebody's name.
