Default Bluetooth connection oem radio AP1 2001

hi,

i am currently trying to find a connector (cable) that goes into the back of my 2001 oem radio.

i have purchased 2 connector cables up untill now which look very similar but do not fit.

does anybody know which connector cable or which kit i need to purchase to fit in to the 8 pin round connector at the back of the oem radio?

i would highly appreciate someone's input on this

thanks
vincent

Does the radio work? What are you trying to do?

Bluetooth? Pretty sure the radio from a 2001 radio is unlikely to have that capability since that technology was just made public and there was no reason to fit it to the S2000 (or many cars). This DIN outlet may (guessing) be for the trunk/boot mounted CD changer. Radio is non-US, the L/M/U button is the give-away, so maybe post this or link to it in a more suitable area?

Default which type of 8 pin connector back oem radio 2001 model year?

hi,

yes the radio does work, i have taken it out of my s2000 to fit a bleutooth module so i can connect with my phone or other device to play some music.

the 8 pin connector at the back is indeed for the CD changer connection.

i would like to plug into this 8 pin connector so i don't need to solder inside the radio itself.

i am in Europe, Belgium, and i am asking the question here because there's a lot of knowledge on this forum.

the 8 pin connector at the back of the 2001 model radio should be the same for US and EU market i assume?

thanks everyone for some input, if i would know which type of connector goes in here it would be a great help, the blue tooth module itself i can connect afterwards.

thank you for some help, it's much appreciated

US cars had a rectangular CD changer connector, so most of us can't be much help.
That said, the connector you have looks like a standard 8-pin DIN connector which should be easy to find.
Hopefully someone (on the European forums?) has a pin diagram, or maybe it being DIN means it's standardized.

Look for clues around page 150-3 in the Wiring Manual. USA but there may be clues there. (Download the manual.)

A few more potential hints:
based on the markings, the headunit appears to be p/n 39101-S2A-G010-M1, I believe made by Alpine.
AP1 US cars had headunits/CD changers made by Matsushita and AP2s by Clarion, so I doubt any US documentation will be useful, and I'm skeptical an adapter made for a US car will work with that headunit.

I'm thinking of the circuits not the physical connection. I've tried but a round connector fits poorly in a square socket.

My post was not a commentary on your (very reasonable) advice, just trying to help the OP from traveling too far down a likely deadend.
Some more poking around shows that Alpines of that generation used what they called M-BUS to connect the CD changer, and the good news is it looks like there are some off-the-shelf solutions that might work.

Don't overthink it; get the Ghost Box from JDi and call it a day.
