The 3-Way CD/Aux Stereo Switch is a compact switcher box allows connection of up to three stereo sound sources, to one amplifier. Here, an Arduino is used to command the TEA688OH signal processor (QFP chip top right) to switch inputs on command. There are two other easy input options for some 2000-2008 vintage cars that have phone or Satellite (Sirius) hardware.

This always seems to be a problem with audio over bluetooth, when you power the bluetooth module and amp from the same source, because those modules are super noisy. I have gone down a different route, but similar outcome, but I had a jaguar ACM installed already, simples!I watched the video by the Indian guy (can't remember the handle he goes by ATM *) that does repair/upgrade videos doing this job. Head units from this era are usually easy to hack, with relatively large components and traces inside and simple signal flows. A simple USB powered unit that converts Composite analogue RCA audio and video to HD and full HD signals via HDMI socket.

Okey, thanks - I have asked the dealer, and they tell me that they need to reprogram the whole car, and it needs to stay over night because it takes so long time.In the case of the Kenwood standard CD changer input, it’s as simple as tying a certain pin to another via a resistor, and the head unit can be switched to the CD changer input and audio can be piped in. Inserting that into the deck gets the CD input selected, and the auxiliary audio can play through on top of the silent output from the CD itself.

A more elegant solution in this case would be to force the TEA688OH to switch to the CD input, or another input, regardless of whether or not a CD was in the drive. The rpi zero runs mpd so the music plays in the car rather than being streamed and breaking up via bluetooth. Come join the discussion about performance, modifications, classifieds, troubleshooting, maintenance, and more! There are many stereos out there with 13-pin CD changer inputs with completely different pinouts that aren’t compatible at all. It sounds bad, but works great as far a AM/ FM functioning and switching to phone using the Tape button.Generally this should work, assuming the voltage range of your input is the same as the cd player or that the amp ic expect. The problem you may have is that a portable CD player may not have sufficient buffering to compensate for the motion of the car.
