Clarkyboy Posted October 15, 2022 Report Share Posted October 15, 2022 Hi This has probably been asked a thousand times but a quick search here revealed no matches. I bought a Boxster with the old head unit disconnected and and a CDR22 jammed into the dash but not wired in. I have managed to get power to the CDR but obviously it is now asking me for a radio code. Does anybody know where I can access this for free or do I need to pay one of the many sites that seem to sell this information?

Daboy3000 Posted October 15, 2022 Report Share Posted October 15, 2022 If Richards code doesn't work i can dig out a link to an eBay jobbie from a couple of weeks ago, it was about £3 and i had the within an hour. Quote Link to comment Share on other sites More sharing options...
Clarkyboy Posted October 15, 2022 Author Report Share Posted October 15, 2022 Thanks Richard. That code worked perfectly, the radio fired up and was searching and finding radio stations. My only issue is that there is no sound output! To be fair I have been rather winging it on connections and yesterday I also managed to get power to the Alpine IDA Unit that was previously fitted, but yet again there was no sound output. That unit did have an adaptor harness and a usb connection, so I have ignored the a usb connector which is also present, which I obviously cannot fit to the original Becker Unit. I may of course have plugged the connectors incorrectly... I plugged the black connector in the lowest slot, brown into the middle and yellow/green into the top. One of the connectors did have a trailing yellow wire, which was obviously diverted to the Alpine head unit in some way. It looked like there had been some serious bodging in the past with some wires just twisted together and electrical taped together Obviously having failed completely in my guesswork approach to fixing the problem, I have now returned to the forum in the hope someone knows how these things should be connected and why I now have a seemingly working head unit but no sound! Thanks again Jonathan Quote Link to comment Share on other sites More sharing options...
Daboy3000 Posted October 15, 2022 Report Share Posted October 15, 2022 It's such a hard thing to diagnose without seeing the state of the wiring. Can you test the speaker wire at both ends? I think that is where your problem is going to be. If you look at the top of the stereo it will give you the colour codes for the wires.

Clarkyboy Posted October 15, 2022 Author Report Share Posted October 15, 2022 The CDR22 unit I have does not give the colour codes for the wiring (the Alpine did). I also have a factory amp in the frunk, so I'm not sure if that makes any difference or whether it was disconnected when the Alpine was fitted. Perhaps I need to pull it out again and take some pictures of the connectors and wiring. Quote Link to comment Share on other sites More sharing options...
Richard Hamilton Posted October 15, 2022 Report Share Posted October 15, 2022 (edited) It is.most likely the the wake up line for the amp isn't connected. Drop me a PM with your email address, and I'll sent you the wiring diagram in the morning when I get to my PC.

Clarkyboy Posted October 16, 2022 Author Report Share Posted October 16, 2022 Thanks Again to Richard, I now have some wiring diagrams and it looks as if the issue is probably the 12v wake up feed for the amp. I can see that his black/red wire has been disconnected as suspected. My car has the frunk amp, but no CD changer. Looking at the wiring again it seems that a brown connector has simply been attached and rewired to the original yellow connector to support the aftermarket head unit. Would I be correct in thinking that if I remove these connections to the brown plug and simply plug in the yellow connector directly to the middle port on the Becker unit that I would reinstate the original connections (the wiring diagram for the amp shows a yellow connector)? I have attached some photos of the wiring I have available, and included one of the aftermarket Alpine head unit, which utilised the current wiring (presumably excluding the green/blue plugs as there are only two connectors) and which again I can get powered up but with no audio output. The usb lead is interesting as this obviously connected to the Alpine at one point, however i have no idea where it goes to. Apologies again for requesting an idiots guide to what is no doubt a fairly simply solution. Either way I would like to have a working radio!

Richard Hamilton Posted October 16, 2022 Report Share Posted October 16, 2022 It looks to me like you only need to remove the bodged wires from the yellow plug, and put the yellow plug into the CDR. 1 Quote Link to comment Share on other sites More sharing options...
Daboy3000 Posted October 17, 2022 Report Share Posted October 17, 2022 (edited) The Brown plug should be for speakers, if you have an amp then I guess it doesn't use that, as Richards says, try removing the bodged wires from the yellow, connect that back up with the blue and green and give that a try. I have seen some bodges, you might need to do more repairs as thats a bad one. lol The usb cable with the screw knob is from the Alpine, no need to keep that if the Alpines going.

Richard Hamilton Posted October 17, 2022 Report Share Posted October 17, 2022 What they have done is to connect the speaker outputs from the Alpine unit to the amplifier inputs on the car. It must have sounded dreadful. Hopefully it hasn't damaged anything. Quote Link to comment Share on other sites More sharing options...
Clarkyboy Posted October 17, 2022 Author Report Share Posted October 17, 2022 Had some time today and removed all the bodged connections to the yellow plug and then reconnected the head unit and...it worked! Sounds good and quite powerful actually. Thanks Richard and Daboy - spot on with your advice. The challenge now is the CDR 22 head unit itself, which was in pretty poor condition. While the front opens for security and to accept a CD, it looks as though someone has had the whole front of the unit off previously. I had to replug two ribbon connectors and reattach the front, but it appears that it is still loose and this occasionally affects illumination of the display and even power to the unit. Applying pressure to the front of the head unit restores things and I haven't even tried the CD yet! Not sure why I have got so excited about getting a 20 year old stereo working again...

Glad you got it (mostly) working. I recently bought an untested CDR22 from a house clearance after removing a butchered aftermarket system last year, the joy in my eyes when i fired up a 1996 mix CD was priceless. Being an ex DJ/music producer I do love my music, the sound quality from my non amped cdr22 is pretty poor, but it just looks right and I have a flat six for my soundtrack anyway. 1 Quote Link to comment Share on other sites More sharing options...

Good work, but have you had a look at the Continental/VDO head units? Modern tech but still a '90's look and feel when fitted in the dash.

Daboy3000 Posted October 18, 2022 Report Share Posted October 18, 2022 True, but then you don't have an original Porsche stereo. Just me being an*l and not really caring about sound quality and features. Whatever I do to the system, it's not going to sound anywhere near as good as the Harman Kardon in my daily, so i'm happy with stock for looks.

I've got touchscreen, CarPlay, all the bells and whistles in my daily but I can't wait to rock a few old CD's. I have huge envy of a friend though who tells me his early 2.5 came with the tape deck in the head unit along with the 6 CD changer. I would love to fire up some old mix tapes! The Continental is an option if I can't get the Becker to consistently work with a bit more fiddling. Quote Link to comment Share on other sites More sharing options...

The Continental is an option if I can't get the Becker to consistently work with a bit more fiddling. I did think about sourcing a tape deck, that is what mine would have come with from the factory. Recently I discovered Porsche had offered a minidisc player, the MDR 32, if it wasn't so expensive then it would have been great, because I have a load of my DJ sets from the late 90's on minidisc but don't have anything to play them on! 🤣 Edited October 18, 2022 by Daboy3000 Quote Link to comment Share on other sites More sharing options...

Clarkyboy Posted October 20, 2022 Author Report Share Posted October 20, 2022 Ummm. No rocking out to 90's era CDs for me. Unit begins to take in CD then stops part way. I also keep losing the display illumination (pushing front of unit brings this back) although I retain sound. It occasionally makes a three tone 80's computer type sound and dies. I think the previous owner may have been sold a pup with this head unit. I will keep fiddling but may be in the market for a replacement. 1 Quote Link to comment Share on other sites More sharing options...
