Navi Service Menu - Messing Around

[bulbon]

Hi,

I've made some mess in a service menu. By accident I've changed one thing in LOADING topic.

And now the navi doesn't want to load any disk. Even the original one. Disconnecting the battery doesn't help.

Is there any "reset" button?

The worse thing is, I am not able to get back to service menu. It doesn't exist any more without system loaded.

Any help?

You changed the country tab - now you must buy a new navigation ECU. What is the year and model of the car?

This is 2004 RX330.

Need to change ECU? Are you sure? Maybe there is a "total reset" button somewhere in navi comp?

Nope. You changed the country tab.... buy a disc from the country you changed it too and then change it back to the US.

Since this is a GEN 3 system there is no other option except for replacing the navigation computer. You can purchase an out of warranty navigation computer from your Lexus or Toyota dealership. The part number is 86841-33060-OW.
