The PIE Aux In adapter will give you better sound, but costs quite a bit more. If you are getting professional installation, the labor costs will be about the same, though.

In the long run, you will probably be happier with the PIE adapter, unless you plan to change out your head unit.

The FM Modulator Relay (SAT-SWB) works well, even with the recently FCC mandated reduced power FM transmitters. It is cheap and, like the PIE adapters, fairly easy to install yourself, if you can get to the back of the head unit. The only drawback is that it takes the demodulated, decompressed, decoded audio, then remodulates it, sends it to the HU antenna (while cutting off the external ariel, eliminating interference) where it is demodulated, again. All this can have some impact on the sound quality.

The truth is that, unless you are an audiophile, the difference in SQ is not that great. You will have to decide whether it is worth the extra cost.

Good luck.

I spent the extra money on a Pie Adapter and I am very very happy, the sound is incredible. the volume on my car stereo is barely on, compared to my fm transmitter days where I had to turn it all the way up to hear anything.

Plus with my Pie adapter I can hook up my ipod in the headphone plug of the ipod.

The model I have is the XM5 adapter which is made for XM radios but the newer Sirius radios work all also. plus no need for the cigarette adapter, this thing powers my radio also.

I went with the PIE after trying a FM modulator in my 97 Taurus. If you have a radio with low output sound but louder CD or AUX output (like my taurus) you may want to go with a PIE adapter. With my car the fm modulator output was low and had a hissing noise.
My X3 PIE adapter sounds great tho, in my opinion it was worth the extra money and just as easy to hook up as the fm mod.
Just remember a fm mod is $30 bucks but then you'll probably spend anywhere from another $15-30 bucks on antenna adapters to hook it up to your radio. So the PIE really isn't too much more.

I Wired FM Modulator Relay/SATSWB/FM Direct Adapter (all of which are the same) is going to remove the static from the interference but it's going to sound more 2 dimensional Vs the Aux Inputs.

You will be so happy with your choice. Even if you were to sell your vehicle they come in handy for the next person who is purchasing it.

If you go to painted antenna's webiste, tss-radio.com, on the menu bar on the left, there is a section towards the bottom that is Auxilliary Input Adapters. You need to find your car's make and model if it is an OEM headunt, because not all cars can do this(For example, my 1999 Nissan Maxima cannot do this without a different head unit).

Thanks for the info. Too bad I need an OEM radio for it though.

There are some PIE Aux In adapters for after market head units.

PIE doesn't has Aux Inputs for every car and not every car can use one.

There are a few other companies that make them as well.

I use the PIE deal on my Dodge Ram and with my Myfi XM the volume was lower than the AM or FM so I had to lower the volume when switching from XM to FM .
I have now switched to SIRIUS and use a Stiletto 100 in a car dock using the same PIE unit and the volume of the FM and the Stiletto 100 match perfectly .
I can`t say it is the MYFI because I also had PIE in my Super Duty Ford and it matched perfectly but that was also a different model PIE for the Ford .
The PIE unit for the Ford I had to connect it to 12 volts and a ground where in the Dodge the voltage and ground must be supplied through the CD changer connection as it had no extra wires to connect for it .
Most important to me is the fact that the CD section of the hu has a wider frequency range than the FM which sounds much better in the end

if you are using an aux input and your volume is too low, you can use this to solve your problem:

Hey Paintedantenna - this would be a cool thing to carry in your shop. that way I could point there instead of an XM store when people ask about low volume problems

At one point I had the PIE interface ,the line LD-1 level amp and a ground loop isolator to help get rid of the alternator whine that was increased with the line level amp. It did the trick and sounded great with the truck shut off . It was used with my MYFI at that time and I did more wire moving ,relocating line level wires in relation to power and or ground wires moved grounds to different locations and if they did cross each othe I made sure it was at 90 degrees . I eventually gave up unhooked the amp and the ground loop isolator and used the cigarette lighter for power instead of the one built into the interface and lived with the MYFI that didn`t sound loud with the windows open but most importantly it was clean and clear sounding like a CD . If any one wants the line level amp pictured in the previous post or the ground loop isolator they are still mounted under my dash just disconnected let me know along with a PIE interface for a Ford super duty XM5-FRDN that works great which is in a box as I have a Dodge Ram for now .
