The only way for the system to be accurate it seems is if you subscribe to Hyundai's Blue Link services powered by Google. I entered an address into the GPS manually and it wound up taking us nearly 20 miles off from the true address, nowhere near the lake/park we wanted to go to. When this happened I hit the Blue Link and talked to a customer service rep., who was able to promptly find what we were looking for and send it to the navigation system.
It is about the worse GPS system ever, takes forever to recalculate a route (15+ seconds sometimes) and this is after an update. Before the update it would take even longer to figure out the new route. Our $99 Garmin does it in a few seconds which is how it should be. The SD card system they switched to isn't nowhere near as fast, which is a limitation of the cheap card their using or the computer within the navigation system itself. Also it should have an option to choose Sun Pass etc. according to your state, the navigation system shows the toll booths and even says Sun Pass but always want's to direct you to the paying lanes on the right...retarded.
