We'll be doing a lot of exploring with our 2005 Highlander (which has oem Toyota GPS system), and I'm wondering whether it would be worthwhile to buy a new DVD full of GPS data. I've driven to a few restaurants listed in the GPS that no longer exist, and driven on new roads that the GPS doesn't know about!
But I think the DVD costs about $200.
Does anyone have advice as to whether the data in a current DVD would be significantly more reliable than 2005 data (both road data, and point-of-interest data)?
Also, I'm assuming the new DVD would just provide newer info, and not change the programming of the GPS system... that is, the menus, screens, etc., right?
