Android Radio audio out to CD changer

[Filibuster]

Hi everybody,

This is the second thread I open in this section during the last 24h.
The other one being the Raspberry Pi for an 2000 Range Rover one.

Since this question doesn't include a Raspberry computer, I thought it merit it's own thread.

For various reasons, my new plan for the Range Rover upgrade probably doesn't include a Raspberry Pi computer anymore, but rather a double DIN Android Radio.

I intend to keep the original Radio with cassette desk, but instead of fitting the GROM bluetooth interface I bought to it's CD-changer IN, I want to hook up the new Android device to the CD-changer IN. Can you follow?

I want the original radio to be able to perform as usual and play FM Radio and cassettes and to have the Android Radio for Navigation, Bluetooth A2DP, calls, etc.
When I switch the original radio to CD, then the music of the Android device should play.

Whether this makes sense is an other question, but would it technically be possible?



I have this car specific harness and wonder whether I can use it to play audio from this radio:




I probably will go for this cheap unbranded Android radio because of the very slim design (depth of only 25mm) and it's minimalist looks.
This way it would look much like the factory setup

Any comment welcome!
