The Envision system was announced last year, initially for retrofit in the King Air 200 and 90-Series turboprops, with subsequent approvals for the Cessna 300 and 400 Series piston twins and early Cirrus SR20 and SR22 singles that dont have Entegra glass. An Envision retrofit wont be cheap, with retail prices staring at $29,995 for the EXP5000 PFD and $13,995 for the EX5000 MFD. However, even with installation, these numbers are competitive with Garmins emerging G600 aftermarket retrofit and with the typical big ticket avionics upgrade that many owners seem willing to buy. Availability is expected for early 2008.
