1. I believe the technical answer is "no" - there's been some discussion lately that this would be a good feature to add (and the display appears to support it, as it dims when in sleep mode).

2. When the unit is in standby, hold down the "ENTER" button (middle of the navigation pad) and the "INPUT" button together. The unit will display the version number on the front panel for about 10 seconds. (And remember, don't press "ENTER" and "MENU" at once unless you want to reset the unit to factory defaults.)
