Looks like a standard mini-B to me. That's not to say they couldn't
overload the pin functions - you can already signal things like bus
resets with single-ended conditions on the differential lines. Could be
as simple as a pull-down on the + line that switches D- and D+ to RS-232
The blob on the cable isn't large enough for anything bigger than an
LQFP32 at most. I really don't expect to find anything that complicated

I figured I would have to keep using my GPS-III (with the display going out), or pick up a simple serial GPS module and put it in a plastic box, for attachment to my Kenwood D7. Instead, maybe this?
