I'd put the A and B trip in the must fix section.
The turn signal indicators are too small and out of the line of site. I miss seeing them frequently.
The three icons in the current trip display take up space and serve no useful purpose. Icons are supposed to either express state (like the high beam indicators), or be a button for performing some action. These do neither. I have never figured out what the squiggly road icon is supposed to represent, and the middle clock icon doesn't correctly represent all the items in the column.
The big problem with the toy car is that if you have a light coloured car, it's worse than the headlight wash for night driving.
Bring back the day and date on the screen (the font on the calendar icon is too thin to be readable in many cases.
The Navigon screen is now in night mode even in the daytime--very hard to read.
The arrows on the bottom popup in the Navigon screen don't show what the lanes do the way the side popup did. I suspect a lot of folks don't realize what they are supposed to represent (at least not at first). Example: If you have six arrows, which ones are straight, which ones are left/right turn only. You used to get a clue, now you just have to guess. Totally awful.
And while we're on software defects, although this didn't start with v7, the fonts on Google maps are just too darn small. If you use the satellite view they blend in with the background and are unreadable. Night view is mostly unreadable regardless of satellite setting.
Information for the driver should be available at a glance, you shouldn’t have to study the display for several seconds. Yes, Apple does is, but no one dies if they have to study the display on their phone to figure out what's going on (doesn’t count the idiots who drive and text).
