bulbon Posted September 11, 2007 Share Posted September 11, 2007 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? Quote Link to comment Share on other sites More sharing options...

What is the year and model of the car? Quote Link to comment Share on other sites More sharing options...
bulbon Posted September 13, 2007 Author Share Posted September 13, 2007 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? Quote Link to comment Share on other sites More sharing options...

You changed the country tab.... buy a disc from the country you changed it too and then change it back to the US. Quote Link to comment Share on other sites More sharing options...

You can purchase an out of warranty navigation computer from your Lexus or Toyota dealership. The part number is 86841-33060-OW. Quote Link to comment Share on other sites More sharing options...
