During my struggles with EQMOD over the last week, I had occasion to try and hook my little matchbox-sized GPS box up to give coordinates to EQMOD. It worked just fine.
I thought I'd pass along the unit info in case anyone wanted such a setup. It's a Holux M1000B, I bought it last year on Ebay for about $80 and used it to feed my netbook PC during a big trip I did last year. Worked in trains, planes and automobiles, including tracking in the French TGV at 300Kph +.
It also comes with a little GPS program to run on your PC or PPC. So now it also feeds my PC+EQ6
I have no affiliation with the mfr, just a very satisfied user. Oh, it works with any bluetooth dongle.
