We are working on finish up the Service Bulletin to support EAB aircraft owners to load GTN V6.51 software. The Service Bulletin is in the final stages of review and we are working to have it posted to the web tomorrow (11/9/18).
When it is available, it will be posted here: https://www8.garmin.com/support/coll...t=010-00G3X-00
Note, the primary issue fixed in GTN 6.51 only affects users with a GTX 345(R)/45R or GDL 88 connected to a GTN for ADS-B weather.
