all i know is in hawaii all the ISx50 series don't come with navigation, the GS series comes with a screen but not navigation. so as for updating your navi for hawaii roads? hmm... not really sure, ask the dealership... or just call up carson toyota in cali being as they seem to be able to get everything cheaper.
oh btw, you don't need navi in hawaii :lol:
trust me after awhile you'll get used our roads here... now some of the roads maybe named a lil funky but the islands are quite small compared to the states that navi really isn't an issue. unless you seriously need it to work. granted most of our streets here aren't laid out like on the mainland but thats one of the things that makes Hawaii what it is.
oh and welcome to hawaii, whenever you get here anyways
