So, the options are (1) wire to a switched source, or (2) remove the GPS from the bike each time I get home.

I would just as soon wire to a switched lead.

What suggestions can any of you offer for hooking into a switched lead under the headlight cowling?

Thanks in advance,

Right on! That's a good plug ... I use it for my heated grips. There are some other switched wires free but all are around the battery area.
I would only use GPS when on the road ... so taking it off the bike at the end of every riding day is a given no matter what. Only takes a few minutes to re-acquire the birds, no?
