Here are my thoughts if I can put them together.
Version 8 plus:
Map can be displayed larger, overlaying controls
Passenger in seat keeps the systems on when driver exits
Customize trip display
Map auto-zoom
Five-band EQ (though I usually leave mine flat)
Extreme temperature climate control safety feature (I would never leave anyone/any pet in a car in those conditions)
Link fob to profile (N/A in my car, no profiles)
Version 8 minus:
Inconsistent app placement
Inconsistent map behavior (overlays controls automatically while driving, manually while parked)
Map behavior necessitates delay and extra click to activate an app while driving
Map behavior necessitates delay and extra click when zoom (etc.) icons fade
Streaming broadcast-station sorting (alpha by frequency!)
Auto-zoom can cause blank map exiting highway until tiles download (No NAV, so I need the map)
Next Favorite button can forward to a Slacker station, but then Previous Favorite cannot back to a streaming broadcast station
No definition to button areas. I don't necessarily need a button, an outline or shade will do. Really anything that's not nothing.
Click already highlighted source to return to browse list
More of a learning curve to use then earlier versions (see all of the above)
Long SuperCharger list (sorted by distance) removed
Manual zoom-out allows longer charger list to be presented, unsorted
To browse stations, one must scroll past a whole screen of popular/recommended stations first
Excessive screen space used with large album art/station logos, wasted space could list more stations
Balance & fade no longer real-time
Anything I missed in either "column?"
I cannot get the above to balance. I'd really like the passenger seat feature, and the map overlay feature if it were always manual and the auto-zoom feature if it were selectable. But I can't give them nearly enough weight to compensate for the annoyances.
