2012 Outback V, with only about 12 hours on it. Just have the factory stereo setup for now, Sony cdx m60ui HU and 4 in-boat kicker speakers. No Amp. While on the water yesterday HU started acting up, was shutting itself off and restarting in the middle of playing a song. Was using the USB input with an Ipod at the time, however later discovered it didn't matter the source of the input. Did this numerous times, could turn it off and back on and would go back to playing, only to shut down again about every 5 minutes or so. After getting home, while trying to pinpoint the issue, it started doing it much sooner, every 15-30 seconds or so.
HU has never gotten wet, all connections seem to be snug, and it happened whether using Ipod or radio tuner. Ground wire seems tight.
Any suggestions of things to check prior to returning to dealer for them to deal with? Thanks for your help!
