Every time we turn around, there's yet another company that previously had nothing to do with GPS, ready to get in the game. Now Harmon Kardon
will be releasing its first GPS gadget, called the "Guide + Play" in the US this coming January. We don't know much about it yet other than that it can play MPEG-4 and WMV files, support SD cards up to 4GB, and will purportedly stay juiced for up to five hours. Oh, and it'll only set you back around $500.
