Group Monitor is a digital feature. The radio embeds GPS data on your signal when you transmit using a digital mode and so any other Yaesu digital radios will know your position. It's similar to APRS but doesn't require a second channel & frequency. So the secondary side of the radio is still available for analog or regular APRS if you wish.
Never got a camera mic. That sucker ain't cheap and seemed a little silly. I dunno, maybe it would be useful.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
