I'm looking to buy a GPS unit to use occasionally for trips to the lakes or wales. I've not used one on a mountain bike before and not upto speed on exactly how most people use them. I understand that tracklogs can be loaded into a unit, which can be used as a guide. How effective is this in reality? Can I simply download a route online and go ride?
Typically I only bother with a handful of 'proper' mountain map following rides a year in the UK so tend to either resort to a map (sometimes getting it wrong) or try to find someone who I can tag along with.
I'm currently in a position where I can get a massive discount on Garmin units and leaving for another workplace has prompted me to think about getting a unit. If it really is as easy as follow a downloaded tracklog then it might get my riding further afield more often.
I've been looking at the Oregon 200 https://buy.garmin.com/shop/shop.do?cID=145&pID=14902
Also any comments on the usefulness of detail topo maps for an irregular user like myself?
