My Accord came with the above but no code number for it. There are a couple of places locally that de-code stereos that I can, hopefully, get mine sorted at. I removed it and put in a JVC CD player. Since then I've noticed that the battery drains very quickly. So I took the JVC out and had no problems with the battery since. On the rear of the Bose head unit is a socket for a CD Multi-changer. Can I use any type of multi-changer or does it have to be a Honda specific type? Was there a Bose CD head unit available for these, and if so, what would be the chances of ever finding one in working condition? Thanks.
