What year of 924 or 944 do you own? I could never find a wiring diagram to verify that this adapter worked with early 944 and was wondering if anyone with one has tried it?

edredas I have a 1987 924S and an '89 944 turbo. Both has aftermarket stereo but it's the 87 that I want to change.

Cool, good luck with your project! I have a JVC in my turbo, but this was my first non-CD player unit. I really like that is can use an SD card which has been even better than using a USB thumb drive since those stick out and get in the way.

Just an update. I installed the JVC unit in my 951 a couple of weeks ago and a PO had cut out the factory connectors but they installed short pieces of wire color coded to the aftermarket harness that seems to be universal these days and did a nice job so it was a simple matter to just color match the new harness. Took about 20 minutes start to finish.

Awesome! Good Luck!

Very true. Most original speakers no longer work at this point despite looking new. There are some speakers out there with tweeters that will fit behind the cover. It’s just hit and miss finding which ones do. If you can find a good picture of one before ordering just check to make sure the tweeter doesn’t protrude above the surface of the side of the speaker.

If I remember correctly, on an early car it should be the upper fuse #9 for the the power sunroof, etc. This runs to the sunroof/radio relay behind the console. Its a rather big relay with a diagram on it and should have all the wiring you need, if it is still in tact. I hope that helps!

So it sounds like you're wanting to replace your stereo with a stock unit? If the installation was done correctly using an adapter, then you should be able to remove it and plug your new one in. However, if the wires have been cut then you might have to track down a harness in order to get the radio to work. I hope that helps!

edredas just bought removal tool. Will see how it goes.

Yes, rather than connecting that wire to the adapter, you can just connect it to any wire that gets a signal when the parking lights come on. I used a sleeve over my wires and was wanting everything to connect through the adapter, but I really didn't have to. I hope that helps!

Sounds like the radio is getting power all the time. If everything is wired correctly, it could be that the ignition itself is stuck thinking that the key is in all the time. Try spraying some lube down in there and see if that helps.

I have come across some cars with completely different wiring. The wiring in the video is the most common that is used on the Reno and Charleston units. Other head units seem to have their own wiring and there isn't much info available on them, so you'll have to use a multimeter to figure out the wiring...

I got this one from Amazon. It was really cheap too! I've replaced it since then though but it was a pretty good radio until the display went bad. Thanks and good luck!

This is actually rather common and most of the time it is caused by old factory speakers that no longer work. The simplest way you can test if the speaker is bad is to take the speaker out of the door and hook up a known good speaker. If it works then you have found your issue! Usually the wiring doesn't go bad and doesn't need replacing but if there is a short then that could be your issue. That said, if the test speaker works then you can probably rule out a short, if it doesn't it could be the head unit. I hope that helps!

Here's a link to a video where I removed the fader switch at the owners request. The fader was broken inside and causing volume issues, which could be the issue you're having. If you are installing a new radio, getting rid of the ancient fader setup might be the best option. On the fader you will find wires running to each speaker and you can just hook your wires there if you wish. I hope that helps! kzfaq.info/get/bejne/fcWhqsemxJuqnqs.htmlm18s

Here's the one I used: www.crutchfield.com/S-7GObYomHE9u/ymm/1987-Porsche-944-Wiring-Harnesses.html

Yes, for the most part. If you have an aftermarket head unit already there’s a strong chance that they wires have already been cut. I also find that these adapters typically only work with factory Blaupunkt Reno and Charleston units which were very common. However, some other factory units may have different plugs. Good luck!

Hi, all the stock radios were Blaupunkt however removal of a Pioneer is similar. Just remove the bezels and you’ll find slits on both side of the unit where you will insert tools. Those tools look a little different than the ones I used but it’s the same idea where you just insert them and pull the radio out. I’ll leave link so you can purchase some.

Also check out my series of videos on the 1984 Silver 944. In them I show how to remove a Pioneer headunit. I hope that helps!

Thanks for all the help man will check into everything!!

Yup!

@@edredas goat!

+Kyle Capaldi I tried to find a wiring diagram for the early cars to verify but came up short. If I remember correctly it doesn't mention that it fits the 924S but as you can see it does. The wiring should be similar to the early 944. I hope that helps and let me know what you find out so I can post it here. Thanks!

Thank you for getting back to me. i will be ordering the adapter so and ill let you know it it fits or not. Thanks again.

In most cases you need a kit to use single DIN head unit a larger double DIN slot. In this case I'm installing a single DIN head unit into a single DIN so there is no kit required. I hope that helps!

I wouldn't think so. At the moment I can only verify that it works on '85.5 944's and 924S if you do the illumination mod that I showed in the video. That said, it may work on 1981 and later 924's and early 944's but I haven't verified that yet!

ok thanks. do you know about any sites where i can find the right adapter? :)

I'm not entirely sure such a thing exists for the early 924's. You might have some luck asking on 924board.org.
