Hey everyone, new user here.

So I'm not a big car guy, and I mostly rely on a buddy of mine to help me out with car issues, but I recently attempted to make use of a cable I bought on amazon, and I'm very lost.

Essentially, I want to be able to play music through AUX on my 1998 Porsche Boxster. My car runs a Becker CDR-210 AM/FM/CD radio.

I did some research, and saw that many people with CDR-220s were able to easily convert their radio to accept AUX by purchasing a cheap cable that plugs into the input for the CD Changer's RCA present on some of the Boxster models from that time.
The main idea is that with the cable, you should be able to trick your radio into thinking your playing a CD through the CD source, while accepting audio from your iPhone through the CDC input.

Here's the cable referenced:
I looked at the product, seeing that it was only for CDR-220s. I consulted a Youtuber who had made a tutorial on installation of this cable, and asked him if the cable would also work on a CDR-210, and he replied, saying that there's no reaosn it shouldn't work, as the cable would still serve the same purpose of tricking the radio into using the CDCs source. This made sense, as the two were very similar radio models.

Fast forward 1 week; my cable arrives. I'm excited to get this thing working after months of riding around with a small portable speaker. I pull out the radio, unplug the CDC plug, and replace it with the aux cable with an identical plug. Fits perfectly.
Fire up my radio, switch the source to CD, and plug in my phone. I play some music through Spotify, but it isn't working. Okay, so I;m thinking I might have to do something after that, considering I'm giving the radio a whole different formatting. I looked on some forums and videos, and finally I found a video where a guy explains how to program the AUX source into the radio by pushing down on a button...that's only present on the CDR-220.

The button is just about the only difference between the 210 and 220; just a small 'TP' button that if held down for 8 seconds, beeps, pulls up 'Becker 1', and allows you to scroll to enable AUX.

I kept messing around with it, trying to find a way to do it on the 210. I tried holding down buttons, unplugging other cables on the unit, putting in a CD to trick the CD source into running; still nothing.
The one thing that confuses me, is that it doesn't seem like there's a reason it shouldn't work, as I'm essentially just rerouting the audio source through a compatible cable.

I would happily invest in one of those head unit boxes that you can get for about $80, or just invest in a used 220, but as a guy who's about to start college, I don't really have the funds to keep throwing money around and seeing what lands.
Ideally, I would love to just find a way to use my CDR-210 and the cable and make it work, but I've run out of ideas. I'm fairly sure that it's possible, as I saw some people discuss on other forums, but I was not provided with an explanation on how they made it work.

If it helps, I can upload some photos of the 210 and the inputs. Any help is appreciated.
