Currently using an old edge305 on the bike and a new forerunner 310xt running. I use routes on the 305 when out on the road and it chirps when I approach a waypoint and points me in The right direction. Its a hassle to make routes tho, involving exporting from whatever mapping site and converting in basecamp and if I go off course or have to change, having g no base map means I’m more or less on my own
Halfords are doing the 800 with 1:50k UK mapping for just under £300 (and I’ve got gift vouchers burning a hole in my pocket) but the question is how useful is it going to be at guiding me round a pretty defined road route? And can it do turn by turn mapping (I think that requires additional mapping but not sure)
