The standard map in the 2012 Hilux is Navteq, yet the Toyota web pages suggest the map provider is WhereIS. But I think it depends on which model / year the car is. Would be happy to pay a reasonable fee, but $320 plus for one update is crap. On another car forum they have also hinted that Toyota only release a new map every 18 months to 2 years... Now if your in a small place and only travel on occasion... May be OK. When you in a major city or need to travel through one, then with tunnels and major changes every other months, 18 months is a laugh. Best option is to not get a Toyota with a Sat Nav system and to but one for a quality car sound place. That way it will work as you expect and you can get map updates at a reasonable rate and as required. Hilux SR5 = Never again... SR with option pack and then addons via non Toyota supplier = functional work vehicle.
