Exchanging Boxster Stereo head unit.
 

Hi
I have a 2001 Boxster and the stereo unit is failing. The unit keeps powering up and down as you drive along randomly. I have been told the contacts behind the front drop down panel are the problem but I have cleaned them to the point they are spotless and still the problem persists. The head unit is a Becker CR-22 with CD changer and amplifier unit. The question is can I buy a straight swap out head unit or do I have to get into changing the amplifier, I can live without the CD changer as I very rarely use it.
Thanks for any help you can give me.
Regards
Paul

Installed a new Alpine head unit with the factory amplifier. I love it.

I bought an aftermarket unit from Crutchfield - I gained Bluetooth, USB and Aux in - plus with the variable color display, I can match the OEM dash lighting.

Sound is way better and a couple years ago, I had already installed the aftermarket kit for rear speakers in the rear storage shelf and with the stock unit, the rear speakers were not powered from the stock amp so they weren't as loud as the rest of the system. With the new unit, the pre amp outputs go through the stock Porsche amp and the rear speakers are powered by the head unit's internal power.

Crutchfield had some decent inexpensive options - since I mainly drive with the top down, I didn't need a high end solution. It was pretty much plug and play using their wiring harness adapter. Took me less than an hour to install.

I know you did ask, but my dash speakers were also going bad and I ended up replacing all my speakers (dash, door and the aftermarket kit in the rear storage shelf. That was a 200% improvement.

+1 for Crutchfield. Excellent customer service. Great product selections from bargain to top of the line.

I had a similar problem that caused the system to power down and then back up. Replaced with JVC BT unit. All good.

Hi everybody
Thanks for the reply's all who contributed. I was looking for a direct replacement to keep cost down, I don't use the stereo very often.
dghii was the JVC BT unit a straight swap for the original Becker unit? If it was do you have the model number
Thanks Paul

Crutchfield has tons of options under $100 and you could get away for $50 depending on what you wanted. I found aftermarket to be a better solution and cheaper than buying another used 15 year old stock unit.

Call and talk to them

Was this just a staright head unit swap? I didnt think this was possible with the Porsche MOST system in the Boxster

I did this
 

It was one of the first things I did with my 2001 S, it was so easy and improved things so very much. The most difficult thing was getting the old head unit out.

Crutchfield is the way to go! Made everything very easy.

Crutchfields not an option :-(
 

Hi Again
Crutchfield looks like an amazing store there is however one slight problem, I'm in the UK. In the UK we have Halfords but they are useless, the shops are manned by young kids that you wouldn't let loose on a $200 car let alone a Porsche. From what I'm seeing it looks like a straight swap is not an option with the MOST amplifier uni which is a real pain in the a$$.
thanks
Paul

I did the same swap with a Kenwood BT unit, and kept the factory amp and eq. Just had to buy a wiring harness of amazon. $9 to wire it all up. It was a direct swap, with no extra brackets or anything need it. However when I did mine, I moved the climate control down, took the storage bin out, and used the extra space to install a tablet in the dash.

If you are wanting to keep costs down, you should replace the factory unit. The JVC unit I installed was $79 two years ago! I sold my factory unit for about $200 IIRC.

I'm sure JVC model numbers have changed and I don't ever remember what it is.

I would recommend considering two things...
1. Adjustable illumination colors ( to match rest of your cars illumination.
2. How easy does the unit connect (and reconnect) to BT?

My unit will connect every time but takes a good minute or two to establish a BT connection, very annoying on short trips.

I've seen a Sony unit that has a nice carbon looking faceplate and multi-color illumination for around $100 at Wally World. I don't know how quickly it will establish BT but cosmetically it would look very at home in the 986 dash.

BTW, get a factory harness adapter locally or at Amazing for under $15. Same for radio removal tools ($%). Installation is easy if you can solder a few wires.

Hi and once again thanks for the great help. is this the connector I need to pick up the audio to the amp from the new head unit.

This is my concern, one which nobody seems to address... I dont think it's a sealy as a head unit swap with the MOST system. You are probably looking at an amplifier swap too.

Can anyone with a 2001-2004 S conform if it's a straight head unit swap?
If so, I have a very good Parrot asteroid head unit with phone kit/microphone that I took out of my previous car that I could use.

For 2001 and 2002 I believe it is a straight swap, very easy and harnesses relatively easy to find to mate with the factory HU. And you can still use the factory amp if you want.

MOST systems are only in 2003 and 2004 986 cars. CDR-23 is in the HU in 2003, not sure on the 2004 (think it might be the same). If you have an amplifier in a MOST car (either the HiFi option, or Bose) - you will also have door "speakers" (actually subs), it is absolutely not a straight swap. If you don't have an amp at all, it is easier since the speaker wires are connected directly to the HU. The HU, amp and cd changer (if you have one) are all connected fiber-optically by the most bus. No aftermarket stuff is compatible. To replace the HU, you would either need to bypass the amp altogether (which requires running the speaker wires to the HU from the frunk where the amp is and thus the current speaker wires), or replace the amp with the HU which still requires running wires from the new HU to the new AMP, since the factory wiring does not have all of the necessary wires to connect a new HU to an AMP. It's also hard to find harness adapter kits that are plug and play to the factory HU and amp harnesses (it's been impossible for me so far). There is a company (cai-store.com) that can get you part of the way there, but there would still be some additional work.

That said, it's not THAT big a deal to replace the HU and amp, just requires some wiring and running wires between HU and frunk (where you would presumably place the new amp). Been done many times before, if you search you should be able to find quite a bit of info.

For your consideration:

Thank you. This was the info that I was looking for. Yes it is the CDR 23 in my 2004 model also.

New head unit fitted
 

Thanks everybody for the help in solving this problem. I purchased a JVC KD-R981BT in the end, it cost about £100 plus £15 for a connector.
The stereo came with a JVC to ISO A & B adapter and I purchased an ISO C to four RCA plug adapter. The process was very simple, I plugged the two adapters into the stereo and then into the existing car's wiring, the only extra connection was the red wire from pin 6 on the ISO C1 needed spicing into the switched feed to power the amplifier. This was the yellow wire in the stereos wiring.

This looks pretty OEM. Can you match the colors? Which unit is this?

Exchanging Boxster Stereo head unit.
 

It's the Continental TR7412UB-OR. The only colour is an amber/orange colour, but it looks like it will match pretty closely. That image is of it in a 993 or 964. I bought one, but I'm just waiting for my adapter to come in. I didn't want to splice into my harness. It has Bluetooth, USB, so forth. Continental also has one with a CD player. I plan to route the Bluetooth microphone to the factory location (left of the gauges). You can find it on eBay or buy it from Tore Bergvill on his website. He sells the systems, but also makes the adapter harnesses. Here's another pic with the illumination on.

The Continental unit is about as factory look as you can get short of of a "Porsche" radio.
They have pretty good reviews. They do cost a little more $150-$200 IIRC

Yes, I think I paid around $180. Pretty reasonable given the appearance is a pretty good match.

Today I installed a Pioneer that I got for $99 from Crutchfield, and it included the radio removal tools and wiring adaptors for free. My CDR 220 had developed a symptom where the radio function worked only intermittently. Pricing a replacement CDR 220 on eBay showed that getting a decent one was going to cost around $300, so it was a no-brainer to get a new stereo.

The install was actually pretty easy, although the wiring instructions that came with the adaptors had the 12v switched and constant supply wires reversed.

The good news is that the sound is so much better than the Becker! I would agree that the new stereo certainly doesn't look as good as the original Becker, but at least I could set the colors to a matching orange. Overall, I'm very pleased.

I didn't realize how much I listened to the radio until it died!

Dulmer - could you give us a review of this one you get it installed?

Sure thing. The adapter harness has shipped, so hopefully will have it soon.

Sorry, I have read through this thread a few times. Still not clear whether I can swap in an after market stereo with my CDR 220 in my 2000 2.7 without replacing the other parts of the stock stereo system. i think mine has the hifi option, so I guess that means factory amp? Thanks.

You should be able to swap the stereo no problem. My 2002 base has the optional Bose system with the amplifier mounted in the front trunk and the rear speaker box. In the installation kit I got from Crutchfield the amp wiring has it's own adapter, which goes from the stock connector going to RCA style plugs that go into the stereo.

Here is mine installed in a 986 with the M490 sound system, very happy with the unit.
The handsfree system actually works with no extra microphone attached.

Looks great! Looking forward to getting mine installed.

Thanks for the pic Dulmer....

Can you take one with both HVAC unit and the radio turned on to see the color matching ?

Yeah, I could definitely live with that. Thanks.

Not seeing that Continental stereo on either Crutchfield or eBay.

Try Bergvill F/X. You can get the adapter harness from him as well, so you don't have to hack up the factory harness.

It's on eBay too though:

Got it, excellent. Thank you. Does the CONTINENTAL TR7412UB-OR have better radio reception? Disappointed with the factory unit. Some of my usual stations barely come in.

I'm not personally sure, as I haven't installed it yet.

What did you use for the doors? Did you get a good seal?

Replacing head unit.
 

Just replaced my Becker CR 220, with a Kenwood KMM BT518 HD. Harness that came with it was 1787 from Crutchfield. On my 2002 Boxster S, I had the Bose 5000 System. I had never heard of the 5000, but it had the rear speaker system, which worked well with the Becker system. The supplied harness from Metra #1787 was fine but rear speakers did not work. I discovered that the brown connector had only 4 connectors, whereas the Becker connectors had 8 connectors. Tracing back, coonectors 1,2 and 7,8, from the Becker plugs were non-existent in the 1787 plugs. Connected the missing connectors to the brown plug and "voila" have superb sound. Any comments or help, contact me!
