Hi, I just purchased a '06 Lexus IS250 SE with nav & everything.

Seems that it still has all first owners settings (speed dial, contacts etc).

Is there any way to reset the system to the factory default settings (i.e. the same settings the car had when it was delivered to the first owner) ?

Thanks !

 

should be some sort of guide for that in the manuals...they're useful

 

try going to the menu and hit "volume". then touch the upper right corner then the lower right corner then the upper right corner and then the lower right corner. that will bring up a hidden screen where you do the nav override. not sure if it has factory reset but u can check. if this sounds confusing look up "2006 is nav ovveride" im pretty sure there is a video on youtube or somewhere but its real easy.
