Last week after upgrading my Ipod Touch IOS to 4.3, I noticed that when I turn my car on, the AVIC stays OFF, and I have to manually press the ipod icon, so it can start playing music. It's like when you turn your car off when playing your ipod, then unplug your ipod and turn the car back on, and your AVIC screen remains OFF until you either plug your ipod back or select other source.

It's no big deal, but if this happens to someone else that means I upgraded
