I started taking the dock apart. this is what I find so far

the dc from the radio section is below .2mv both channels

The output impedance is about 7.5k

Cutting four wires and adding RCA plugs is all you need to connect the tuner.

BTW the bass boost button causes some weird mono so you won’t be able to use it and keep the output in stereo

Next I will find and change the coupling cap.
