The manual says I may hear "noise" when I use this input and sure enough I am hearing a high-pitched tone from speakers when listening to my my Pioneer Inno XM radio. The car's manual says to eliminate the noise I should use the device's own battery instead of the cigarette power adapter. This works, but HOW LAME! Anyone experience this? I need an alternative to allow me to use the car's power to run my Inno.
Thanks!
