Fits perfectly, just have to run some wires from the connector to the MAX232. I thought about a 2.5mm jack, but I wanted 4 wires for the GPS (data in, data out, gnd and power) Could get by with 3, but am always changing batteries in GPS & would like waypoint output.

Good idea about changing the config bye first! I was going to mount the MAX232 in the vacant spot where U3 (high side switch) goes & wire it up dead-bug. Kind of ugly, but should work. I think I'll use the MAX232 for port-a as well. With my Palm, I sometimes have a hard time getting command prompt (have to hit enter many, many times).
I'll post some pictures whan I get it done.
