I have the Garmin Nuvi 200W with the 2008 edition of Navtech maps. Is there a way to make updates to a street intersection? The main intersection by my house needs to be updated, when the map was made one of the streets wasn't finished and did not go through. Now the street is completed, but my Nuvi always wants me to take a 3 mile detour to get to the highway rather than just make a left turn on the newly completed street. Besides that, the Nuvi has always been accurate and correct in navigation so I don't see the benefit of spending $80 for a map update just to correct the one intersection.
I have sent this info to Navteq already, so hopefully they will update there maps. But my question was if I can have the Nuvi always assume that I can turn left without having to buy a map update. Can I customize the map that is already installed in my Nuvi?
