The unit does not time out when your update subscription expires.
Each update typically includes fixes for errors, new coverage for older vehicles, and new coverage for newer vehicles. If you work mostly on 2010-older then the coverage it has is probably good enough. If you work on 2012-newer you probably always want the latest updates.
Updates currently cost about $650.
