On a Discover Media Generation 2 (MIB2) unit, what function precisely is invoked by pressing the On/Off/Volume knob for 15 or so seconds?
This appears to be an undocumented function in the VW user manuals (well, I haven’t found it described in any of them) and there appears to be some confusion about what it is in various places on the Internet. Some say it is a reboot of the system, others describe it as a reset, or even a hard reset. To me, a reboot and a reset are two entirely different functions. I see them as follows.
A reboot is simply shutting down the system and then restarting it, preserving all modifications that have been made to the system and all personalised settings. A reset, on the other hand, is restoring the system to the state that it was in at a specified point in time (such as the time when the car left the factory = factory reset), losing all subsequent modifications and personalised settings.
