My 2003 GS300 with Navigation just now acting up. Last week I could not get the NAV screen to turn on at all, I was unable to control anything etc: climate, navigation, fan. Now the screen is back on, everything is good on it but the Audio, the Audio is OFF, and I by pressing the POWER button would not do anything. I even check the Fuse and it is good. My AUDIO is not working, please help....

Check all ur connections to back of navi and stock amp could have a broken or fried pin connector or just a loose connection
