I'm thinking about getting a Pioneer DEH-2200UB, which advertises itself as having controls compatible with iPods. I will be using it with my Samsung Fascinate in my 2005 Honda Civic. Is there any way to tell if a car stereo is compatible with Android Phones (by compatible, I mean the controls can be used to control my Winamp player, or as a last resort, the default player)?
Note: I am asking for a general solution, not one specific to my particular car/stereo/phone combination (though feel free to give me a specific solution in the comments).
