New Headunit Ideas?

I have the stock MB Quart headunit in right now and already some of the push buttons are not working! Im going to get a new one from the warranty but I want to eventually replace it with an aftermarket one for more features and tweaking ability. Anyone have any suggestions for a good unit that is reliable and also if possible works with the stock MB Quart remote on the driver side? If thats not possible, I will also need suggestions on a replacement for the remote. Dont want to get rid of it becuase trying to ask drunk people to turn the stereo down is a nightmare and its nice to have control while driving back around to a fallen wakeboarder or whatever.
