That's kind of what I was thinking.... Do you have access to a voltmeter and a spare 3.5mm plug? .. If so, insert the plug in the FM OUT jack and measure the voltage at the pins. You should see about 5 volts appear there when the receiver is on. If not, then that is your problem.

I just picked up my adapter the other day and got it installed and setup and I am soooooo much happier now. I haven't been able to listen to my Stiletto in my car for over 2 months now, it's been sitting at home on the stereo being used via Wifi.

I have absolutely no static whatsoever. The only thing I have left is the crackling SSSSS sounds on some of the channel announcements. If anyone knows what I mean.

I have that.......Depending on your Head Unit.....Sounds like your "Highs" are high. I have mine set up that way...Some Lows....Some Mids..and High Highs (if that makes sense)

I understand this jack will send low voltage power to the fm direct adapter which in theory disconnects my terrestrial signal..

Does anyone think this is possible and its my fault its not working today?

So I called Sirius, and since the radio is under a year old they agreed to send me a new unit, Lets hope that does the trick..
You shorted the FM jack. The jack is meant to be used with a specific plug that has both positive and negative poles. Sticking bare wires in it creates a short.

Default wires and voltage

Does anyone know the wires and voltage for the fm direct relay. I have one of these installed in my car want to use it for my Zune as well and I have seen that the modulators for the zune can be opened and have an antenna wire soldered to the circuitboard to transmit the FM signal. but I would need to know how to get the relay to kick over to shut off the external car antenna.

Is the plug the goes into the back my Starmate 4 Universal dock a "mini" stereo plug? Would I be able to hook up a mini splitter and feed both my iPod and Starmate 4 into the FM Direct Adapter?
I had mine (with the FM Direct adapter) on the same frequency (89.9) for the entire trip from Akron, OH to Laurel, Maryland and never heard a peep of static.

Default FM modulator not working

Thanks to this post! I installed one of these in my mother inlaws car and she said her AM radio wasn't working. I checked it out and things were acting a little funny (not like this post said it should) because both Sirius and FM were working at the same time but no AM. I pulled the unit, opened it up and did some investigating. I was totally confused at first because things were not laid out the way I'd thought they'd be and there was no way for the "FM Out" on the Sirius unit to trip the relay, ever. I hooked up 5V to where I thought it should go and traced it back to the antenna output. It turns out the two wires exiting the unit were installed backwards! I bought it off eBay for next to nothing so I wonder it that was the problem, or maybe it's a conspiricy to sell bad units by old fashioned radio . I resoldered the wires in the right place and BAM it worked great. You could now hear the relay click when the Sirius unit turned on and AM and FM worked when off. Here's a picture of the unit and the two wires I had to swap. In hind sight I should have just cut the cables outside the box and switched them that way but I wanted it to look as clean as possible. Well, I just thought I'd share my experience for anyone else with a bad unit.

Default Did not work

I purchased a Stiletto and car dock. Installed it and had a hiss using all of the options, Sattelite,library etc...... I purchased the antenna adapter and it made absolutely no difference. 03 Ford Ranger, Factory Stereo

I'm with bigbill117; can an already installed FM direct adapter be easily used (with some re-wiring of course) with your average 3.5mm equipped FM transmitter? I'm getting rid of my receiver but I'd love to keep the direct adapter in and use it with an mp3 player.

I've installed the FM Modulator and I notice no difference. I then got another Modulator and still the same prob. I've checked the FM output and getting around 2.5 volts. I'm assuming that is not enough to get the Mod. to work. I know it needs 5. I'm thinking the dock is fried then?

I found that it was a lot clearer but also a lot lower in volume. Did anyone else notice this? I find it better to just listen to my ipod fm transmitter. Any comments??????????

Bringing this thread back to life. I am having same issues as everyone else. Stiletto 2 with dock and fm mod relay. Installed into a dodge ram truck. No AM, Regular FM loss of quality.....background hiss on Sirius. Yes Sirius is a lil better than using the fm transmitter....but not worth the money. Looks like Im taking dock and transmitter back to futuredump. Unless someone has some ideas. Maybe I should take apart like someone else here did.
