So, finally I've made it :-) First I've thought that the ECU, which some of you referred to, was the computer mounted under the dash, nearby the screen. Disconnecting the battery which was inside this computer was useless in my case. BUT, there is another battery - in the navi disc reader. And disconnecting THIS battery solved my problem :D In my RX330, navi disc reader is in the trunk. regards to everybody

For how long did you disconnect the battery. I've done it for 30 mins, and nothing has changed. Are there any other than memory backup batteries in ECU?

I've got the possible options in LOADING menu: JP-TSW US-TSW AUS-TSW US-AVN_BT US-AVN_UBT US-AVN_BL CHI-TSW I've chosen AUS-TWS probably, but not sure if it wasn't US-AVN_BT. What is the difference between US-TSW and US-AVN_UBT for example? For now I start to look for LOADING.KWI from Australia.

I've the same problem. Changed country tab and do not remember what was selected so I don't know what kind of disc I need. Maybe somebody could post all possible country selections found under "country tab". As I remember there was JPN, US and ... and don't remember :-) Knowing the country we should try to find corresponding LOADING.KWI file and take a try to start the navi with it. I'm guessing ...

This is 2004 RX330. Need to change ECU? Are you sure? Maybe there is a "total reset" button somewhere in navi comp?

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?
