Back in January, we got an XM radio (Audiovox Xpress) for my wife's 5. We had issues with the FM modulator in there (I'm guessing because the receiver is in the front of the car and the antenna mounted at the back.
We tried other FM modulators, but with mixed results.
FInally, I installed a SureConnect kit.
It actually works very well... It's designed to attach to the base of a traditional metal mast front fender FM antenna, but that doesn't work so well in the Mazda thanks to the VW style mast. So, I took off the panel on the roof at the in the cargo area, peeled the headliner back just a bit, and clamped the terminal directly onto the antenna cable where it connects to the base of the FM antenna.
Alas, crystal clear sound (or at least good enough for a 4 speaker factory sound system) and the Audiovox receiver's cradle has an auxiliary input for my wife's MP3 player. It doesn't work as well as the aux input in the dash of my Element, but it's certainly an easier and cheaper fix than tearing the dash apart to install an AuxMod! There's a similar product for Sirius radios as well.
Here's the installation guide on the SureConnect
