However, you can't have it both ways. The only way an iR device knows it HAS Iridium connectivity is to try to connect. The point of the aggressive retry is that this is an emergency satellite communication device. This retry applies to the mail checks. It also applies to things like sending a track point, or sending a message. It is not intended for use indoors, or buried in your pack, or under water, or whatever. This "problem" is well known. All iR devices have behaved this way since inception. The product managers at Garmin have apparently decided that this implementation is the least of the available evils.
