I have a Garmin Nuvi GPS unit that has an 8 inch screen, Voice Command, BlueTooth Connectivity, and Life-Time maps update. I already have added more than 1,000 campgrounds in a POI list using Garmin's POI-Loader.
Can the 430N unit be loaded with POIs such as campgrounds?
I know that to update maps is usually very expensive.
What other features does the 430N have over the NUVI?
Is there any advantage in having the 430N built-in rather than having the NUVI set on the dash?
