I installed the Alpine CHMS620 with the PIE (Precision Interface Electronics -818-678-3690) Acura/Honda to Alpine CD Changer adapter cable Part#ACU/HON-ALP. This is the only extra cable you need (my car is a '99).
I put in an (Alpine) CHM-S630 off eBay. It worked fine and cost +-$200. However the mounting bracket does not fit and needs to be modified. It was a simple matter of turning the mounting plate around and drilling new holes (very easy). The CHM-630 is smaller.
