Is there a way to install some sort of bluetooth radio or add an aux port somewhere? On a Mazda6 S 2004. The radio seems very integrated into the dash.

 

this is what ive found. looks like I can replace the dash too.

XCarLink USB MP3 Player Integration Kit for Mazda #XCLu-MAZ - Revolution Performance Motorsports!

 

Im not aware of any factory Bluetooth options.

There are various aftermarket standalone Bluetooth products.

I believe there is a plug/socket in the back of the head-unit for a CD stacker, which you can buy a AUX socket wiring loom & plug it it.

 

ok, that may be the one i linked above. I am still on the fence if im going to do that, or put in a double din dash kit and install an android radio led.
