To my surprise, and delight, I was able to go off route and be routed back using prompted recalculation without the XT recalculating the remainder of the route, or recalculating the route to the next via point. As expected adding a detour to the route will force a recalculation to the next via point but a casual detour does not.
Congratulations on getting back on the bike. I hope the Cataract surgery went as expected.
In my mind, prompted recalculation is one of the strengths of the XTs. I'm glad you were able to experience that yourself.
