PRODUCTS AFFECTED:
Garmin GI 275 Multi-function Instruments with System Software Version 2.53 or earlier are affected.
CERTIFICATION AUTHORIZATION:
TSO Authorization
TSO Authorization does not provide installation airworthiness approval. Separate installation airworthiness approval is required for type-certified aircraft. Notification of revision to any Garmin STC(s) will be provided under a separate service bulletin.
COMPLIANCE:
Optional: This Service Bulletin may be incorporated at the owner’s discretion.
PURPOSE:
GI 275 Multi-function Instrument System Software Version 2.60 provides the following updates:
NOTE
If installed, GTN Xi Software Version 20.30 (or later) and TXi Software Version 3.50 (or later) is recommended before loading GI 275 Software Version 2.60.
NOTE
Database sync routing is affected by this change. Systems with GTN™ 6XX/7XX (v6.72 or earlier) or GPS 175/GNC® 355/GNX™ 375 (v3.20 or earlier) interfaced to G500/G600 TXi (v3.50 or later) or GI 275 (v2.60 or later) no longer support database sync. Databases will need to be loaded onto each GTN 6XX/7XX and GPS 175/GNC 355/GNX 375 unit. This limitation will be fixed in future GTN 6XX/7XX and GPS 175/GNC 355/GNX 375 software versions.
