Options To Replace Dead Ml System?

[phaseshift]

The Mark Levinson system in my 2003 ES300 has partially died. The whole control panel is dead, except the rotary knobs that control volume and tuning, and they only work while rotating. I can't, for example, turn off the unit, or turn on the display for navigation, or open the panel.

Dealer says replacement is the only option.

I know the ML system is heavily integrated into the car. Do I have other options? Are there aftermarket solutions?

I don't care about the cassette deck, but I still want to play CDs. It would be cool if I could get something that would receive HD radio, and have an aux input for my iPod. And of course, I still want navigation.

Does anyone have suggestins?
