2013 Sundance with the the Genesis 2.0. Unit won't work on any buttons at all after powering up trailer this spring. The red power light is on, no buttons work and no display at all. I"ll take it out to check connections and fuses, In 2024 what is the best replacement stereo that is an exact fit for the existing hole in the RV wall. I see a lot of old threads that mention old discontinued models but no current threads. Any help is appreciated. thx in advance
