Compromises

doing some final tests today i discovered :-( that the pin 21 remains at 2.25V if the iPod is powered externally. This is really bad news because i con not use it the way i intended to control de radio.

At this point i have two options, use pin 21, or install a switch. I will check with my pillow and hope to have a decision tomorrow.

	switch	pin 21
good	iPod can be docked and still use the radio iPod can be used with headphones more generic solution	no switch
bad	manual control	have to disconnect to listen to the radio/CD

It looks like the switch is the winner! the switch being more generic will also let me put an extra AUX input that i can use for a scanner or other device!
