Does everybody use navigation all the time? I used it twice this year. I always think I need navigation on my GPS units but in reality eh not really. I'm either riding with somebody else who knows the route, somebody else has navigation on their GPS and I'm just following them, I have my phone, or 97.685% of the time I already know the route.
Could be because most of the time when I'm riding somewhere new I'm usually mtn biking and navigation is useless for that. There is also the problem of spending $300 on a item that you don't use most of the features on and could be broken anytime you wreck which happens a lot while mtn biking. I run an old magellan 315 that I paid $70 new for because it was an outdated POS but it does everything I need including the navigation I don't use.
