Title: Poor electrical noise filtering
Review: I purchased this product hoping I could play my song downloads from my smartphone to my factory radio.While the product does the job, it has an annoying shortcoming. It allows electrical noise from my car's engine be audible through my FM radio. Since I enjoy listening to classical music, this is a big problem to me.If I am accelerating, I can hear an annoying high-pitched "whirring" sound through the radio. I can also hear other "whirs", whistling, and popping noises especially during quiet moments. The noise is not present during normal radio operation - the noise is only present when tuned into the frequency the transmitter is set to. My car has all stock components so the noise is not due to some modification or add-on.Might not be a problem with some cars since different car models have different electrical components with different degrees of electrical noise, but this product is not so great with a Jeep '06.
