I've done some internet searches but not really found much in the way of solutions. I recently replaced my PCM2.1 with a Pioneer NEX. It's great but i'm missing FM a little. The reception is horrible and Pioneer has traditionally been pretty good about radio reception. Does anyone have a solution to get that reception back?

I read about a cayenne (?) that installed a HF specific(?) antenna. Is that a solution? how would it work with my new radio? would I have to route the antenna wire all the way to the back of my radio? How would I even do that?

I have a 997.1 coupe if that has any bearing.

The OEM FM antenna cable should plug right into the Pioneer head unit. Who did your install? Slide the unit out and look in the back of it to make sure its connected.

hi... as DC911S says, check the installation on the back of the radio... the dash kit used should have come with the antenna conversion cable... if installer did not use that cable it might be the cause of the bad reception - or no reception at all... OEM antenna connection to PCM has a special connector that needs to be converted if u install aftermarket... you can see what the cable looks like in this kit (green connector cable in the pic):

Right, there is a connector that adapts the OEM FM antenna to the Pioneer headunit. I'm guessing it was not used and he actually has no antenna connected at the moment.

The OEM FM antenna needs an adapter to plug into an aftermarket stereo. the PCM has 2 antenna connectors, one black and one yellow. From my research, yellow is for GPS and black is for radio. I connected the black to the adapter and went into my radio. I get some reception but it's pretty terrible.

Watch this......

THis is probably what I need but I can't find one that seems to be for porsche. The ones i've seen have two connectors, usually for VW. does anyone know if those common amplified adapters are Fakra connectors? maybe I connect both the black and yellow independent antenna cables from the car to those two connectors on the adapter? and then the single line from the adapter goes to switched power (which I've run from the fuse box)?

I found the Metra 40-EU56 but the connectors are so close together- i don't know if the separate connectors from the car (black and yellow) will fit.


I could go with a non-name brand one with the connectors on separate lines, but I'm wary about mediocre reviews. That could be that they don't know that they need to connect a cable to the radio's antenna on lead though...

Look around in Crutchfield or call them...

They have helped me out in the past.

I bought the head unit at crutchfield and installed it myself. not difficult but the adapters sucked. I'm not particularly happy with them right now. The power adapter they sent me had the 12V connected to the ACC, which I had to splice and fix, and there was no mention of the fact that I had to run my own ACC- their adapter just had a line there doing nothing. I always thought Crutchfield stuff came with full installation instructions. It doesn't. It makes me wonder why I bought from them vs. Amazon. I guess this is the last time.

What's the FM sensitivity rating spec on your new receiver from the spec sheet? Might be that it doesn't have good FM sensitivity. You want one with a spec of 8 to 12 dBf.

12 dBf according to Crutchfield for the AVH-1330NEX
