Just bought our first Lexus and so far, we're thrilled with the car. Long story made short, The car was originally purchased and owned in California and we recently had it shipped to Hawaii. To our dismay, the navigation system (Generation 4, or so I've been told) does not include maps for Hawaii and my dealership has informed me there is no mapping available for my vehicle with the current navigation system installed in the car.
I can't imagine I'm the first one with this case and would like to had a functional system in my car. Can I just buy an upgraded DVD for the system, or do I need to upgrade the whole thing? What steps do I have to take and what equipment do I need to purchase to have this system work on the islands? We live on Oahu if that helps at all.
Thanks in advance.
