User: Since when did the SR22 include a glass cockpit
Assistant: Since February 2003 Cirrus started to offer a glass panel for the SR22. First the Avidyne Entegra was offered to customers. Also retrofits became available for older SR versions. In May 2008, Cirrus revealed the "Cirrus Perspective" glass cockpit, which was based on instruments created by Garmin.

Until today, Cirrus is including Garmin glass cockpits in it's aircrafts.
