the other day I noticed there was a delay in the radio comming on when I started the car and today it will not come on at all. in addition the navigation has no sound and there is no beeps from the voicetronic thing.

Of note, I just had the dash computer replaced which effected my blinkers and all of the display in the dash, but the radio worked. The dealer is still attempting to get the dimmer dial to work with the new dash to controll the light up and down. not sure if they are connected.

anyone have any ideas about this?
