If you have experienced your 7th Generation Nano stopping when switching audio sources you are not alone. This problem is limited to Nanos with firmware 1.0.3 and earlier installed. This is not a problem with the audio unit but rather the iPod triggering a sequence error, failing to report track time after switching audio sources. Apple has been notified of the problem. To get your iPod playing again you must recycle the ignition.
Affects 2012-2013 Civic and 2012-2014 CR-V models.
