Thank you. I don't think I'd mess with external AA, as the Edge series is more expensive than the eTrex one... So more faffing for more money, actually.
The eTrex 30 sounds good, so does the 20. It seems the eTrex 10 does not allow to load any map, there is one included with the highways around the globe and that's it. A bit diminutive, even if cheap. I'll go to the 20 or 30.
Which advantages would the Edge series have over the eTrex?
But bnayal's comment worries me. Has someone found a way to make the thing notify before a turn?
Thank you for the very clear and comprehensive links!
Thanks,
Nicolas
