Mnme31 Posted December 27, 2009 Share Posted December 27, 2009 Can anyone help?!! I just purchased a 2002 Lexus SC430 and the navigation screen reads "Disk Read Error. Insert Disk." I want to purchase the 8.1 version as mine is a version 1, but i would first like to make sure the navigation system is working. Can anyone help me reset this. I've read other posts that suggested disconnecting one of the battery cables, and possibly the cables to the unit itself. I'm going to try this this afternoon, if that doesn't work i will try dismantling the ECU and looking for a reset button. When i hit the reset button (provided i find it), does the battery cable need to be on or off when i hit the reset button? Quote Link to comment Share on other sites More sharing options...

This sometimes helps. iom Quote Link to comment Share on other sites More sharing options...

This sometimes helps. iom I already tried that and it didn't work. I also disconnected the batter cable and it still gives me the same error. I've read in some posts to try and reset it, but i'm looking inside the ECU and i can't seem to find the reset button. Quote Link to comment Share on other sites More sharing options...
