What kind of TomTom should I buy for using with my bicycle?

Question

My mother bought a TomTom and it's got a bicycling feature, which I'm highly interested in. It's called TomTom One 3rd, and I was curious if the bicycling feature was any good, and if there was a better one.

Answer 1

a water proof one

Answer 2

I also have the TomTom 3rd Edition. I think its great. I use the walking feature which works perfectly.
