I need a new GPS bike computer that will mainly be used for road riding: However, I also have a 60km mtb race coming up where we are required to load the course map into our GPS units, so it will also need to be good for route finding on trails, as well as data recording for road riding/training (primary use).

I dont have a power meter, although I wouldn't rule one out in the future, but I do have a Wahoo tickr HR, so it would need to be compatible with that.

Any recommendations?
