Ah.

Hm...

I don't like the idea of relying on batteries. I wouldn't care much about geocaching.

The ideal GPS receiver for me would *support* battery power, but also have some easy way for me to give it power from the Empeg's serial connector. I don't mind cutting some wire and soldering a little bit to do it, but I don't want to have to open a brand new GPS receiver up to do it.
