+1 on the Garmin Quest 2. I've been using it for the last year as a speedo/nav unit on my streetfighter Honda and have been REAAALLY happy with it. Wateroproof, cheap, looong battery life means you don't
have to wire it into the bike. And as long as it comes with the newest software it has the same number of waypoints and info as some of the newest GPS units.
Only complaint has been that it does take a bit for it to recalculate routes. But for 200-400 bucks less than the newer equivalents, it's a hell of a bargain.
