Hello,
I have been using a 410 for the last year (31000+ miles total), both on bike and in car. Honestly I have never had a single issue with it. I've kept it updated and works fine. Battery is quite good on it if your not hardwiring into the bike, about 6-7hrs use.
I choose it as there was a cash back offer from TomTom at the time, and that it has nice clear display and came with lifetime map updates and traffic updates.
I would recommend it.
