Exchanging Boxster Stereo head unit.

[pachinnery]

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.
Regards

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.

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.

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!

Any updates on how the Continental radio works? I'd like to replace my CDR2200 soon. What else looks period correct?

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.

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 ?

[sfkjeld]

Yeah, I could definitely live with that. 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.

I wish I'd seen those Continental units before I bought what I put in!

My guess is your amplifier is not getting the 12Vdc signal to turn on. Look at your amp in the trunk and look for power on two leads, the main power lead and the lead that turns the amp on.

My amp isn't getting power among a few other issues. I went through the pin outs and diagrams. I'm pretty sure that I have the wrong harness. The simple harness can't possibly work with my sound system. If I look at the current wiring and the Continental and Becker diagrams I see the problem:

• My current wiring does not use the B block (apparently this is unused in HiFi option/Nokia cars)
• My current wiring uses the C block pins to send the signals to the amp; the Continental diagram doesn't show that the C block pins are used for anything other than the C4 and C6 pins for SWRC.
• The only output to the amp on the Continental is the B block which explains why I have no sound because it is not being used
• I therefore need a harness that goes from the Continental B block to the existing harness C1 block. Do I also need a line-out converter (LOC)?
• Also, there is no ground pin in the Continental head B block. Does my amp need that?
• Reference https://rennlist.com/forums/993-forum/896189-installing-the-continental-tr7412ub-or-radio-6.html

If the above is correct then the other/M490 harness should work. This is what it is supposed to do:

Swap of Terminal 86s and 30 pins (switched and permanent 12V)
Wire for connection to Nokia/Bose amplifier power on circuit
Line Output Converter (LOC) for connection to existing amplifier

Looking at the picture it looks it is exactly what I need. It also means that not having option code M490 does not necessarily mean that the simple harness will work.

What stereo option do you have? Which amp does your car have?

No option code but a front mounted amp (nokia I think) and Cd changer. Its an ROW car.

When you disconnected the the harness from your old stereo, did it have the yellow square plug? If so, you probably need that second harness I posted yesterday.
