Avidyne has issued a "Mandatory Service Bulletin" (MSB) regarding its "Release 7 upgrade" due in the third quarter for Entegra primary flight displays. The MSB responds to some pilots' apparent interim action of using the displays in combination with Garmin GNS430 units upgraded to WAAS-capable 430W, though the devices are not presently compatible, according to the Avidyne. The software incompatibility is specific to Avidyne's EXP5000 PFD and will be corrected in the Release 7 update due later this year. Avidyne has not yet announced a specific release or a specific price for the Release 7 update. Initial testing of the Garmin GNS430W has shown that EX500 and EX5000 MFD units will eventually function properly together. Avidyne plans to send all Entegra owners who previously received the Release 6 update a notification when the company begins scheduling the Release 7 upgrades. Signup will be available shortly on the Avidyne Web site.
