Hi George, For your G5 system, you want to run the most up to date software available on the
G5 software download page. You would not want to reference any LRU software included in a G3X Touch EFIS software loader card, if you do not have a G3X Touch. Coincidentally, we actually have a software update for EAB standalone G5's that will be made available very shortly, v8.44.
Using the same link above, Click the Download button. You will find revision notes for each software version on this page.
Thanks,
Justin
