Ok, I have the AVIC F700BT wired into my maxima. I was driving along with the ipod playing and I turned off my car. when I went to turn the car back on, my navi recognized my ipod, was reading the info being sent from the ipod, but was not outputting any sound. Any ideas what could have happened within the time I turned off my car to when i turned it back on? I checked my connections and they are all solid, so...WTF?!

Thanks!

your AV1 setting probably got switched off.

Yup, it did! The output mode got changed when my battery died on me! Whoops! Thanks!
