The Nissan Path

Hey everyone, and have a newly bought 2016 pathfinder platinum. I've already noticed that the radio volume will cut out. Whether it's the sat radio or DVD player, the volume will drop down almost to mute, then come back up where it was previously set. Also with the radio I've noticed that the preset channels will reset back to random ones after turning the vehicle off and back on again.
Any ideas of what is wrong with the radio unit or wiring?
Thanks in advance
Shaun

Why fuss with it Shaun? Take it back to the dealer and let them worry about it. That's what warranties are for.
