Hi, I have an 05 LS430 with Nav. About two years ago, I had the Lockpick Blue installed to override the lockout when driving and to auto agree to the "I Agree" screen.

All was fine. Then about two months ago, every once in a while when I started the car, the Lexus screen came on, but the Nav stayed blank. After 15-40 mins of driving, the screen would flicker and come back on.

Now, the Nav screen wont come on at all. The screen works fine with the audio and climate, it just stays blank with the nav.

I had the Lockpick Blue removed and no help. Past post indicated that it may be a fuse. Does anyone know which fuse and where it is?
