I would really like Cycling specific routing.
I assume Garmin would like to entice users from the likes of mapmyride and other similar sites to use Garmin Connect instead for course planning instead, Garmin are producing cycling specific GPS systems, using a generic routing option that handles both runners and cyclists is not acceptable, with the resources Garmin have I can't believe they can send a cyclist the wrong way around a roundabout or along a 'one way street' the wrong way, very underwhelming to say the least.
The Edge 810 with cadence, HRM, microSD-City Navigator NT represents quite an investment, to be honest I expected better than routing that by default can potentially send you off course; unless you want to break the law that is.
