"N37.76579, W123.10245. No worries"

Actually, one worry. When co-ordinates are given in the ISO standard format DDD.ddddd that usually means there is an engineer doing the numbers, not a navigator.

Is anyone actually using the ISO format for navigation, rather than either of the conventional navigation formats? DDD.MM.mm or DDD.MM.SS ? Even having just the latter two introduces errors when folks mistake one for the other.
