 The installed Toyota GPS, while fun to use with it's large touch screen is DVD based, and the disk provided with my NEW Sienna was two years out of date... does not even have my street included (5 years old).AND... Toyota wants a ridiculous $250 for an updated disk!You can purchase a much better GPS, more features, and lifetime map updates for a little more than half that.Just stick it to the face of the Toyota display...Come on Toyota - get reasonable.A NEW car should at least have a current verions disk... and be provided with updates during warranty.
