In my home town all of the FM slots are already filled and as you drive across town you need to look for an open channel to be able to hear the Audiovox satellite radio. And this also is a problem when I travel across the states.

Previous radios from other manufacturers have had cables with switches. This switch will remove the car's FM antenna from the radio and only the signal from the satellite radio gets into the car's radio. It is a pain for most people to connect this cable and would most likely be a professional install. But it keeps all the other broadcast stations from interfering with the satellite FM signal.

I'm also disappointed by the quality of the sound. The coding scheme seems to leave a lot to be desired. This is really noticed on the spoken word. The unit creates a lot of heat for something so small. The audio level coming out of the unit was too high for my cassette adapter. Even with the audio turned all the way down on the Audiovox it was still distorted on the cassette adapter. It took an aftermarket attenuator to bring the audio level down to a workable level.

I do like the display of the unit. It is rather easy to read and has a couple of scroll modes. And the Sirius customer service unit was very quick to activate my radio. The programming is good. While this radio has it faults I'm sure it will be better in the next generation of radios.

Use the AUX Port (Rating: 4.00)
Review : This is a great product for the car. You can use this product two ways. You can broadcast it over a FM station, or if you have an AUX port in your car radio you can connect it to that. If you use the first option, expect to have sound quality issues. Like all FM transmitters, the sound quality is dependant on the strength of the FM station not the unit itself. I personally use the second option, and the sound is excellent.

I didn't use the mounting kit, because I didn't want this permanently mounted to my car.

The SIR-PNP2 Receiver does run hot. This is an issue with the receiver, because it also runs hot with the SIRBB1 Portable Boombox. So far I haven't had any problems.

The Sirius service and channel lineup is great. The only place I have reception problems, is streets surrounded by trees and overpasses.
