First post here and first attempt of audio DIY, please be indulgent
I am looking for a bluetooth module to hide in several old cars (and my A/V receiver if it works well) to listen to music on OEM stereos. I already read some topics here, but I am not completely sure of my understanding. Here are the specs:
- high quality sound,
- analog output,
- no amp needed,
- usable without programming, flashing, or adding buttons; just soldering,
- looking for pairing while it's not paired (no buttons),
- single PCB preferred,
- the smaller the better,
- ideally powered by 12V DC,
- Power consumption doesn't matter.
The Sure AA-AB41136 seems to be a safe choice :

Smaller modules as the CSRA64215 look more convenient, but I didn't understand the differences between various PCB designs, and I am afraid they sound less good and they aren't plug and play, as mentioned in the 2nd red note here :
In conclusion, is the Sure AA-AB41136 a good idea? Would a CSRA64215 or CSR8645 chip be as good? Are there better modules for my need?
