Does any one know how to reset a ES300 2002 Nav Sys. I get an error message that says can not read data check to see if DVD is correct.

Have something to contribute?

You can try pulling the fuse for the radio/navigation system from the fuse panel for 5-10 minutes or can pull the negative terminal cable from the battery for 5-10 minutes. If you pull the battery cable you will lose some presets though, like radio and seat settings, etc.

What disc are you using? I would try an OEM disc.

First, the ten digit part number on the disc should be 86271-3303X; the last digit does not matter. If you have something else besides a -3303x then you have the wrong disc installed.

Second, did you select a different country in the LOADING TAB section hidden within the diagnostic screen? If YES, then you will have to buy a new or remanufactured navigation ECU. The part number is 86841-47020-OW.

Hope this helps.
