There are other options for use with a PDA but none I've found for use
with the 3700 series.

IMHO there are two solutions.
Get a double slot CF expansion jacket (use one slot for a CF GPS
receiver and the other for a memory card).
Or get a bluetooth+CF expansion jacket and a bluettoth GPS receiver.
I have the latter setup, works very well with various programs.
Both solutions don't require any wiring setup (always fault prone).

In flight, I just connect the Ipaq to my logger's NMEA output, which
feeds data to the flight computer, also.
