I have an 06 3G TL with Nav. I turn on the car and the audio system has no power and the "Ok" button will not respond when the Navi is initially starting up. I pull the audio fuse and it appears fine, then when I reinsert, power resumes to the audio system and the "Ok" button will work again on the Navi. It works for a day or a few days, then randomly when I go to start the car, the audio doesn't work.

Anyone experienced something like this or have any ideas?
