I am looking to possibly replace my faulty DVD unit on my 04 TSX. Just wondering if a unit from a 2006 will work. If so, is there any loss in functionaliy or any quirks I should be aware of such as certain buttons on head unit triggering other than expected responses? I kinda heard before that it will work for the 04-06 Honda Accords but not sure. Any definitive info is appreciated. Thanks!!
