problem with MB Quart stereo

So just bought a Mobius LSV and immediately my volume increase button on the MB Quart stereo in the dash compartment stopped working here and there and today on the water stopped working completely! The volume buttons on the driver side control unit work fine. Anyone else having this problem with the stereo and if so any way to clean it maybe or take it apart relatively simply and fix it? I have a couple other loose bolts and minor problems throughout the boat so maybe I will just take it in to the dealer and tell them about it and have them repair or replace it.

this is what warranties are for!

yes warranty.. i have the mb quart and the black box went bad within a day of getting the boat.. they sent out a new black box and all was good......

Yea that is what warranties are for! I just wanted to know if there was an easy, quick fix but I will just add it on the old new boat list and let them deal with it. I will probably eventually replace the unit anyway for something with more features like better EQ and better RCA voltage outputs for the amps!
