Will need to get an installation adapter for a 2005. This will provide your chimes as well as your Retained Accesssory Lead.
If you have the BOSE system you will have to either bypass the amplifier that is mounted in the center console or get a compatible interface to use it.
PAC makes adapters to fit your radio to the factory wiring.
They (Joying) asked me if it had an amplifier and I told them I wasn't sure. I'm glad you were able to clarify that for me. I really wasn't sure where it was.
It does have the bose system.
So Looking at amazon this is what I'm coming up with that I "think" I need.
let me know if I'm missing something.
