Anyone know how, or have info as to how I can ,or even if it is possible to put these features on a Nuvi 1300?
I did this and it seemed to work for Juctionview. My map still does not show speed limits. Any suggestions as to why?
Speed limits usually are embedded in maps.
Just to add to what was already said, not every street has a speed limit embedded in the map. Interstates and state highways are definitely marked as well as major town/city roads that lead to the highways. The side roads in a town or city are not as likely to be marked.
