So a buddy just bought a GNC-215. This is a fairly complex radio with VOR LOC GS in it. I shudder to think of hooking it up and learning how to operate it.
The original manuals do not mention intercom, but there is a service bulletin that addresses an ICS, presumably done with a software update.
His radio was delivered last week from Spruce (forgot to tell him about Stein) and I find myself wondering if he got the latest update.
I assume that if the enclosed operating handbook addresses it he has the update. If this is an older radio from the inventory, it will not have it, and I suspect a trip to the factory will be necessary. Anybody here with recent experience on the 205/215 radios?
