CM644UL Secret Menus - Non-Nav
I've searched every seemingly possible source to find a secret menu for my 2015 Crosstrek radio unit. I've searched the model, subaru's site, the unit's manufacturer site, EVERYWHERE and I can't find a hint. It feels like I've found ways to access every other car radio's secret menu except mine.
So I'm calling out to every forum I can, please, PLEASE, help.
Specifically I'd like to turn off the loudness option. I also have the option where the audio turns up/down depending on speed turned off, but it still randomly gets quiet even if it is off. The only satisfactory option in the unit is the sound restorer which just seems to make the audio louder, but it still randomly gets quiet.
