I have a 2004 Cavalier Sedan with the stock CD player (not MP3). I want to get a new CD player with Bluetooth capabilities. I found this one
https://www.crutchfield.com/p_105KWR...W-R940BTS.html and was going to get the https://www.crutchfield.com/p_120952...-Dash-Kit.html , https://www.crutchfield.com/p_120AXG...Interface.html , this https://www.crutchfield.com/p_12040G...a-Adapter.html , and do their wiring harness service https://www.crutchfield.com/p_264PAS...s-Service.html . I looked at some YouTube videos and it's more than I want to get into, so I was going to get installation locally if I can. One of the videos that covered a huge date range of Cavliers and was installing a Pioneer mentioned that the door chimes and turning signal sounds go through the radio and you needed a chimes retention kit. The rep on chat at Crutchfield says the harness will take care of that. I am not sure and want to have everything I need for installation as the shop that does stereo installs only installs things bought there, so I am going to have to find a mechanic if possible. I did notice the harness covers RAP, but I don't know if that covers the chimes or not.

So, do I need anything else? If so, please suggest items at Crutchfield or Amazon if possible as I need to get this done soon due a law change and cells. Thanks.
