That's kinda what I thought, FAADAN. I'll need to get a card reader w/usb plug & a 1-2Gig micro SD card. I should be able to get those for < $20 so that's not all that bad. Just wish I knew what the updates were, or knew where to find out.

I don't have a map card, yet, either ... and probably won't get one until I find out whether or not this unit will make my fishing more productive.

Anybody have any thoughts on what card reader brands SHOULD NOT be considered ?? I'll probably get a Sandisk Micro card, if that has any bearings on what card reader works best with them.
