How long did you disconnect the battery? I did this twice. First time I opened up the rear compartment and took out the navigation ECU, and took it apart to do the reset, and it worked. Second time I simply disconnected the car battery for over night, and it also resetted. Bad part is, all other settings were lost as wel. Thanks for your reply. It's been a while since I checked this forum last time. Will try this weekend. Thanks again!!

Hello, I have a 2003 IS300. I am having a problem with the stock stereo system. When I first turn the ignition, there is no sound coming from the stereo. CD, radio, iPOD via GROM for iPod interface. After 15-20 min driving, I get the sound back. Does anyone have similar problem like this? If yes, can you tell me how to fix this? This starts happening a week ago. There was no changes made to the car recently. Things I have done so far, remove fuse and put back in after a several min. No luck, disconnect battery for a several hours. no fix Any suggestions appreciated. Thanks!

Hello, I have done the same thing with the 2003 IS300. Tried unplugging power, tried to reset the main board on ECU reset button, but could not find. Can anyone send me the reset disc? Thanks. sanbashi112@yahoo.co.jp

I believe you can select regions from on of the menu screen (regular menu , not from the hidden menu screen). I have done it, unfortunately, I have a navi that is not working, I can not give you specific instruction. How did you reset the ECU? After I am successful with that I can help you on this.

I have this but not sure if this the right thing to do... fix page?

Did you figure out how to reset? Thanks,

YES YES YES....HALLELUJAH........It finally worked. I opened the ECU unit, unplugged the wore that connects to the battery that saves the memory, the whole system was reset and it was very easy...... here is the link....let me know how it works for u guys http://www.clublexus.com/forums/showthread...ad.php?t=167666 Hello, can you kindly repost the link? I am having the same problem now... Thanks!

Is your case same as mine? I have done something wrong and cannot have the Nav running...

I have 03 IS300 with stock navigation. Someone showed me how to override and I was checking around menus. After I checked the Map selection, and pressed OK, I get the screen like this and stuck. ----- Caution Error: System unable to access the program. Incorrect program disk. Please insert proper disk. ------ I reloaded the DVD but the screen remains. Anyone have any idea how to fix this? Thank you in advance for your help. picture
