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:

For installations with G500/G600 TXi Main Software Version 3.61 installed in aircraft with only one GDU, or with an EIS Only GDU, Garmin recommends incorporation of this TSO Service Bulletin as soon as practical.

For all other installations, Garmin recommends the incorporation of this TSO Service Bulletin at the next scheduled service interval.

DOCUMENTATION CONSIDERATIONS:

The G500(H)/G600/G700 TXi Pilot’s Guide (190-01717-10) Rev P is to be provided to the owner/operator if not already provided.

NOTE
Database sync routing is affected by this change. Systems with GTN (v6.72 or earlier) or GPS 175/GNC® 355/GNX™ 375 (v3.11 or earlier) interfaced to G500(H)/G600/G700 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 and GPS 175/GNC 355/GNX 375 unit. This has been fixed in GTN software v6.73. This limitation will be fixed in future GPS 175/GNC 355/GNX 375 software versions.
