Regarding downloading to a onboard navigation system: Yes, that would be a cool feature, but writing the enabling code is fraught with licensing details and there's no way we could offer this and still provide this program free to members.

There are about 15 different online mapping programs utilizing the same data point databases -- some are quite good -- some are not -- but all were built for a specific user.

I look forward to hearing if the RTA Custom Mapping program works for you.
