Mike, I'm trying to picture how one would use a serial cable that's only 8 inches long. I have a Sportrak, and that's the only GPS receiver I've ever seen, so perhaps the Earthmate works differently. I can see that it would be good for storing it in the pouch on the BN case, but how would such a short length of cable allow a user to either wear it on their shoulder or put it on a dashboard. Just wondering. (smile) Peggy
