Thanks Scott. That would probably be easier but still difficult to manage I think. Actually, I've come to the conclusion that this is a requirement where old tech still provides a better solution: I use Orux for on-board navigation but it doesn't have a way of marking good bits that I can use while riding my motorcycle and by the end of the day its usually all too much of a blur to remember where they were. Better to stop for a coffee and get out the highlighter pen while its still fresh in my mind.
