How do I find my TiVo software version?
From TiVo Central, select Messages & Settings > Account & System Information > System Information. The software version is listed on the Software Version line of the System Information screen.
Note: If the box is in Guided Setup, press the following sequence of buttons on the TiVo remote to display the software version: THUMBS UP, then THUMBS DOWN, then PAUSE and then PLAY. To resume Guided Setup at the point you left off, press SELECT.
