My plan is to integrate a standard Motorola vehicle hands-free kit to my '04 PCM2. This includes using the Porsche microphone and Porsche cell antenna.

The current difficulty is that the Porsche antenna has a very unusual connector which must mate to either a standard mini-UHF or a standard TNC connector.

Anyone know where I may get such a coupler and what it is called?

The antenna lead on the right goes to the Porsche antenna, the lead on the left is to the phone.

Thanks for the help.

 

BTW, I already struck out at Radio Shack.

 

The Internet is a good thing, thanks Al Gore.

It appears that the unknown connector, on the end of the Porsche antenna lead, is a FME female.

The coupler is available from Moby Enterprises.

It appears that the coupler I need is a CA-2313.

The FME female to female coupler shows this end clearly.

 

Is the porsche Cell antenna something you added to the car, or does it come factory fitted, and if so, where did you find the lead?

Thanks!

 

Porsche builds each vehicle with a custom wiring harness, including only the wires and connectors for the vehicle as built from the factory. By eliminating these extra wires and connectors Porsche is able to maintain the Cayenne as the class value leader.

Ifin they added the $20 extra in materials they would have to bump up the vehicle price.

The down side to that decision is that, to add any option, the vehicle must be ripped apart, big time.

My 4/20/04 post, in this topic shows the Porsche antenna, which is only one of many components required for adding this option.

 

Thats what I figured...

thx

 

This was NOT ordered from Moby Enterprises. They had a $50 minimum order.

This was instead ordered from Cables & Connectors, Inc. Their part number is: RFA-8254 and they had several in-stock and no minimum.

 

wingless,
are you planning on using the existing microphone (which I believe is used for Bose AudioPilot cabin noise measurement) or adding a second (identical) microphone for the cellphone only?

 

Lewis,

The built-in microphone, part number 955 642 310 00, standard with the PCM2, is a dual microphone, as shown in this post. One is dedicated to the Bose AudioPilot, the other is dedicated for usage with the telephone.

My plan is to use this existing dual microphone, leaving the Bose connected as-is and connecting the unused half to the hands-free kit.

 

I'm assuming the 2nd half of the microphone is the same (electrically) as the first half; i.e. electret, so it will need a bias voltage.
The AudioPilot microphone gets a bias voltage from the amplifier, so I'm assuming the Moto handsfree kit supplies a bias voltage as well?

 

My assumption is that Porsche selected a telephone microphone that is compatible with a vehicle hands-free kit. I do not have any information on this microphone other than what I've posted.

Thanks for the information.
