Hello, sorry if this has been beaten down to death but I have a factory tape player and I just want a din.. I don't want to put a head unit in it (I have a screen/head unit in the double din part so I don't need the 3rd din for a head unit) I just want the 3rd din as a place to put my ipod, or something. If I buy the 3rd din from Honda or from hondaaccessories, are those 3rd din kits only for head units or are they smooth inside? thanks!
