if you plan on using the ex-v6's steering wheel remote then it doesn't work. i attempted this swapped between my 6th gen dx and ex. otherwise it works fine.
one of the head units (the one that says T-xx for CDs) didn't read CD-R's as well as the other one that i swapped from the sedan. make sure you get the right one if u plan to listen to a lot of CD-R's
