Don't know if anyone has an answer for this question yet... bugs me too. same year, same model.. es300 2002... anyone knows where i can get the updated discs for the navi too would be helpful. I bought some off of ebay but im getting an error "cannot read map dvd" or something like that.. heard somewhere that there's possibly a software update disc that needs to be run first??? anyway.. Im having all kinda trouble with this car. Only had one working key too.. no fob. Car's clean and after all these years still has low mileage and was VERY WELL maintained. It was a steal. Loving the way she drives though 🙂 Proud to be LOC.
