I was always content with my 510...until i spent a week cycling around Seattle, constanty lost, always pulling out my phone (having a backup battery spared me). I mostly try to be open when I ride in unfamiliar places and something that allows me to search for a place while on the bike, go there, then search for a new spot has its appeal. If I was planning a serious tour, then I would do the extra work of pre-routing. I'm a little confused by "funky" routing options, could you elaborate? i read some good reviews, but have also read some bad ones. Maybe I will see if REI's warranty extends to out of state customers since there's none in my pitiful little state. thanks
