The BMW Navigator II is functionally identical to the Garmin StreetPilot 2610, so any information you read here or elsewhere concerning the 2610 will also apply to the Navigator II.
The Navigator II has a few minor software features that the 2610 does not (RMI screen and ability to turn the touchscreen off), however, those are not big deals.
Garmin sells a videotape that explains in detail how to operate the 2610. It is Garmin part number 010-10527-00, and sells for USD $16. You might want to purchase it and view it. You can find more information about this videotape here
