Thanks guys, I'll check out the models mentioned!
Sputnik - I drive a '90 XJ, so sort of setting it on the dash in the windshield there's little chance for sustained reception. I've wedged my eTrex in between the dash and windshield somewhat regularly, but it's starting to peel the rubber strip around the outside from holding it there, and it doesn't stay very well. Reception's kind of a problem, and having my GPS in the window like that kind of throws me off when I'm driving, so an external antenna would definitely be nice
Edit: I don't mind too much about mapping features, but how upgradable are the maps on the garmins? It says the factory maps can't be altered..What's up with that?
And what about the 76S? It doesn't have a features list, I'm thinking maybe it's not in production anymore..Do the "marine" features of the 76 series get in the way at all? I highly doubt I'll be taking it on any bodies of water other than wading to go fishing, so these features would just kind of be redundant to me...I doubt there's any way to remove them, so how prominent are they? Are any of the button's specific to marine features?
Thanks again!
