Can anyone tell me if putting in a disc that is not the correct disc for the 2002 SC430 Nav system will "fry" the Nav system or will the system just not be able to read it? Also, will inserting the correct disc do any damage to the disc if the Nav system is in fact fried?

 

...I don't think it will fry the system. A couple of years ago, I purchased a nav disk that was not compatable with my system (gen. 2/3). The message "not able to read" or something similar to that,popped up on the screen. After a few more tries, I just replaced it with the original disk & it operated ok. I later purchased the correct disc & had no issues

 

I have a 2007 gx470 with a navigation system and rear entertainment
my nav screen say
please contact dealer everything else works radio/climate
I was able to find the self diagnostics trick
and code reads 01-DD 110
i will attach pictures
any help would be great

 

You won’t damage it. The CD player will simply ignore any disc that is not compatible. Now I’m curious what kind of Nav disc are you trying to use and why?

 

I'm curious if there's any open source updated map that will work with these.
