The Bose in my 08 G37 will not come on when I first start the car. It seems to be much worse when it it is colder. Eventually after driving for a while (maybe 30 minutes sometimes) it will kick on and be fine. Any suggestions?

 

Does the screen work at all? I'm not sure how the 08 is laid out, but on mine, all console controls are displayed on the same screen. I'm wondering if the screen works when you go into settings and such...or when you change the temperature of the HVAC, do you get an indication on the screen?

Or does this only affect the sound from the music?
