Portable with Winni chip
I just did quite a bit of shopping for a GPS that supports CMAP maps, the format the Winni chip usues. I settled on the Northstar 657, but I did not come accross any brand that are portable and support CMAP.
My friend has a Garmin, likes it, and he says it does what he needs out on the water but the map is not as complete as Bizer's CMAP.
