Tried this in the 430 forum, but perhaps not enough people..
Have an 02 sc430 w new nav disc gen 2/3, version 3.1 oem; and the icon representing the car on the screen is blinking. Is this normal? I think the original nav disc - it wasn't blinking. Can anyone with a gen 2/3 can confirm the blinking is abnormal?

thanks!!

and, if abnormal, any fix?
