I recommend moving the three nav button labels down one space each to maintain consistency with the rest of the navigation system's interface, which is typically centered vertically on the page.
Because the 'Navigation Version' screen is consolidated with the 'Map Update' screen as Map/System Version in my proposal, I recommend removing 'Navigation Version' from this page.
I recommend adding a screen that displays the temperature both inside and outside the vehicle. While the driver can choose to see the outside temperature on the 'Dot Matrix Liquid Crystal Display' (between the tachometer and speedometer), there's no option available to show the vehicle's internal temperature. Also, some drivers may prefer to always leave that LCD display on a different setting, such as 'Trip', 'MPG', or 'Range'; so giving people the choice to display the temperature—both inside and outside the car—on their nav screen would be very convenient.
