So I have wanted to play my spotify music in my truck for a while and have been trying to come up with a better way to do it than just using an FM transmitter. I want the best possible audio quality I can get.

I'd like to just solder a Bluetooth receiver board into the stock head unit somehow. This is one I found that seems like it could work:

Lots of people add aux ports to their stock head units so could I just do that and then plug this into it? Idk how I'd solder in the power source, but could this work?

If I did do something like that where would I need to solder the aux cable into on the stock head unit? Is there an open channel or something that will accept it? It'd actually be kinda cool if I could solder it into the AM radio channel because then maybe I can switch between FM radio and Bluetooth by using the switch on the front of the radio.
