Guys, you may be thinking here of the AS355 Autopilot option.
This is the SFIM 318T system. It is primarily a Stability Augmentation System (SAS) with higher modes of operation making it an Autopilot system. There is also an optional Flight Director with Heading, ASI, ALT, VSI and NAV (Including approach & back course modes). The FD can be used independantly or can be coupled to the autopilot. An optional comparator of which is required for UK / European IFR certification.
It is a 3 Axis System and does not have 'Auto Hover'.
