Hey folks! I just have an idea to integrate bluetooth module into my old but nice 2005 TSX.
Just need to find out aux line with left and right channel wires and ground.

This is for my ACURA TSX 2005 (stock radio without navigation)
Hey folks! Finally I got this hooked up. I found module that support both left and right channels + and - auxilary connected instead of SiriusXM port (25$) (also has Iphone charging cable and aux cable)
Also I got bluetooth module from amazon (10$ for 2 pcs). See pictures and feel free to ask me any questions.
BT(small module) can be hooked up to 5v wires and not use USB port to make it more organised. There enough wires to route all of this into glove box.
Will share pictures later. Enjoy!

This project can be upgraded to better but this works perfect and with good aftermarket speakers (Higher quality Polk Audio (front doors and tweeters) and good JBL on rear shelf) works verrryyy good! And I am enjoying my favorite music!
Feel free to ask questions and I hope this will help you to convert your good stock radio to better =)
Peace!

Hey , can you post links to the Bluetooth module that you are using ?? Thanks De5~

Hey De5 wassup, Here you go https://www.amazon.com/dp/B01EUZ90II?ref=ppx_yo2ov_dt_b_product_details&th=1 They have option with USB as well. Just take a look And here is a BT receiver: https://www.amazon.com/dp/B09R4JXWDW?psc=1&ref=ppx_yo2ov_dt_b_product_details But you can get your favorite... This one works very good and picking up my iphone automatically once I get into the car and turn on head unit. There is a 5V connection you can see on the diagram going to HVAC display. You can also get power to BT module from there and hide module where you like.
