I've been deliberating what to go for. I see loads of people still using the etrex, but the fact you can't charge them from a dynamo if you don't want to use AA's is a bit off putting. But then I keep reading in reviews of newer Garmins that the battery life is only around 5-6 hours if you're using navigation mode, which is the main function I want. So I'm guessing it would mean having them on near constant charge?
I was under the impression you could power etrex units from USB. You might need to use a non-data cable and it won't charge batteries in the unit but it will power the unit.
