Have an older stereo without Bluetooth, but want to upgrade to Bluetooth without paying for a brand new stereo? Look no further than this small BT module. Connect the RCA outputs from the MIL-BTREC module into the RCA aux input from your stereo, and wire to 12V power and 12V ground.
Note that your older stereo must have rear aux in RCA's.
Now sit back and stream!
