We have the 2007 chrome finish "Executive" brand head unit. I think it would be okay in a house where you have 110V all the time. But in our motor home where I shut off the inverter to conserve energy, the Executive quickly defaults to a simple DVD/CD player. It has been a very long time since I fussed with it, but I recall it does not save any settings, and no feature to scan for local radio stations. I would fuss if stationary & plugged in for months at a time like spending winters in Florida, but being on the move all the time, it's limited to playing DVDs & CDs.
Across the board for all types of stereos, I wish manufactures would reintroduce a high tech equivalent to a tuner knob, base, treble, and a joystick to adjust speaker balance & fade. Each Blu-Ray, DVD, CD, and radio station is different and changing these settings for each situation through menus is not practical.
If or when our Executive dies one day, I would likely install a Blu-Ray player like Paul (Doneworking) did.
Sorry John & Carol for redirecting the subject. I hope you get resolution with your firmware.
