PCCM+ Install on 2001 Boxster with DSP - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Hello,

I have a 2001 Boxster that I just installed PCCM+ in. The car came with the CR-220 radio, Hi-Fi sound system (490), Digital Sound (680) and the remote CD changer factory options. The PCCM+ head unit powers up fine but I don't get any sound from the speakers. The installation instructions are horrible and I had to redo the connections a couple of times. Here's a list of the things I determined while doing the install:

1) The alarm connection to the radio frame only needs to be removed and taped in cars that have PCM1, my car doesn't have it so I left it connected.
2) The ground line they instruct you to add to the amp connector is only needed on cars with PCM1, my car doesn't have it so I left that connection alone.
3) The Sirius/XM tuner connector replaces the blue antenna connector in the stock 3 connector block. I removed the stock blue connector and replaced it with the Sirius/XM tuner connector and the connected Sirius/XM tuner I bought from Amazon.
4) I installed the MOST box on the frame and connected it to the PCCM+ head unit, my car does not have MOST but this shouldn't hurt anything having it connected.

Here's a link to the installation guide - https://static.nhtsa.gov/odi/tsbs/2020/MC-10179274-0001.pdf

Anyone here install PCCM+ in a similar car and come to different conclusions, have issues getting sound or have any advice?

Thanks in advance!

Looks like my issue is likely #2, I need to install the ground line. I'll give that a try later today and update this thread with the results.

That fixed it. Replaced the wire at pin 17 with the ground line, changed from CAN to AMP and did a Factory Reset. Paired my iPhone and now everything works perfectly.

I helped a friend change to PCCM in his 03 Targa. I was going to suggest the CAN to AMP change. That's what got us.

Hi, I'm struggling with this now with my 2001. The instructions are crap.

1. how the heck do you remove pin 17. I don't see how to open the housing. It appears to be a solid piece of plastic.

2. What is a Factory Reset? How to do it?
