ALOT of times when I crank my car and my F90BT boots up, my iPod doesn't show that it is connected (though it is). I have to disconnect then reconnect and then it will show up everytime. My iPod (a 2 year old nano) has the latest firmware, and my F90 has firmware v.3.02.0100 - which I think is the latest)

This is a bug that came with the Pioneer 3.x software, it no longer sends a strong enough wake up signal to the ipod reliably.
