Here are a few of the features removed
- Street view preview: Gone.
- Route and alternates: Gone. You have to go back to the directions page in Maps to select a new route (easy enough - just tap the "x"), and those routes' times and traffic details aren't updated based on your present position, as far as we can tell. Hopefully that gets fixed.
- Layers menu: Gone. Replaced by satellite view toggle, and traffic is displayed by default (gas stations, ATMs, restaurants etc. are all gone).
- Other options: Screen dimming is gone (presumably this is now automatic), shortcuts to search, set destination, and help are gone as well.
- On-screen zoom in / out buttons: Gone.
- Search: While driving, search would allow you to find something while en-route. Gone. Critical for this writer.
