Hang on a min....
I don't have a Via model in front of me, so I can't say categorically that you should still have all those features, but I do have a fully updated "Start 25"(which is supposedly a "lesser" model) to try.
Now, if the options are on a Start, I'd like to think at least SOME of them are still somewhere on a Via....
The colors have changed and it's hard to see the streets on the map. I have found no way to change colors in 2D view.
To change my map colours, I go to Settings, Map colours...
The first screen changes the day colour for 3D view, the second is night colour for 3D view, the third is day colour for 2D view, the fourth is night colour for 2D view.
Do you not have those options pages?
Are you getting confused by the 2D map
view when "Traffic" is selected to show? That has it's own very bleached out colour scheme, but deselect traffic in the options at the bottom and your normal colour schemes come back
The name of the street you are on which used to be just above the status bar is gone. The name of the street you will turning onto next is no longer there.
Both of these are set in Settings Advanced settings (Show "street names" and "next street name"
The map will no longer automaticlly zoom in at intersections. When you enter a new destination and it shows a map of the whole route and you press the "done" button, it will no longer automaticlly zoom in to your starting location. You have to do it manually.
This is also in advanced settings (a later screen) "Enable automatic zooming in 2D view" and "Enable automatic zooming in 3D view".
As you seem to be missing so many menu screens I know you have a 2-button "Easy menu" model and the Start 25 isn't, but are you on one of the models that has an option to only show all or only some of the menus?
When I pointed the above out to customer service, they could only tell me that that's the way it is with the update.
I wouldn't trust them to know their donkey from their elbow....
In summary, at a stretch I could be convinced they may have dropped the auto-zoom setting, but I'd be amazed if the current and next street names had been ditched on a Via.
