Getting ready for a Thanksgiving trip. I have an audio book downloaded from the Public Library to my iPad2 I want to listen to. My truck has an Audiophile stereo with a little plug where I can plug in a MP3 player etc. and play from it on the road thru the truck speakers....Can I play my book this way? Do I need some adapter that I did not get with the iPad2 in the box when I bought it? Also can I charge battery from car cig lighter if battery runs down on iPad2??? Thanks and I'm sorta new to this and retired and so forth so my learning curve is big at times but I am trying.
