Pcm2 Installation Question-plugging It In.

Recommended Posts

I just got my PCM2 unit today from UPS. It appears that their are 3 antenna ports on the back. 2 right next to each other(one marked antenna and the other diversity PCM2) and one on the back of the navigation module on the bottom with no marking.

Which cables do I plug into which. Does anyone have a diagram. I would guess the GPS antenna goes into the navigation module, and the FM antenna into the one marked antenna. But what is the diversity PCM2 one for?

Attached is a pic, any ideas...

Thanks for the response, but I'm still confused. The refered posting was for a Cayenne, and so some applies.

I still don't know what the diversity antenna is and what the indicated antenna connection is. Atleast I'm now sure about the navigation antenna lead for the gps.

Does my CDR-23 have two antenna inputs, diversity and something plainly marked antenna? I guess I'll pull the radio today and look. I'm just trying to figure out if I ordered everything or do I need more parts for an additional antenna...



p.s. I bought the main system used from a fellow boarder who replaced her's(hint-hint) with an alpine unit in her SY 996, with muffler bypass. :)

OK, pulled the cdr-23. It looks like it only has one antenna. So I did a little google search on Diversity, PCM and Porsche. It appears to be a signal enhancement antenna for FM reception integrated into the windscreen. I live in the NY/NJ area and we have awesome reception. So I guess I can't hook that feature up. I guess like retro-fit Litronics on earlier 996's and the factory only auto-leveling, diversity antenna requires ordering PCM from the factory.



p.s. I will take pictures when I do the install and post them. First I'm waiting for some parts from suncoast(i.e. gps antenna and cables).
