ok Im installing sirius stiletto to my car. I used the all teh wires . And with the FM extender it has TERRIBLE static. without it i get alot of static at high volume. then i relized im getting static on all my radio stations. So i unplugged the power from the ciggerette lighter. And as soon as i get rid of that. My static goes away. As soon as i plug in my plug the static comes back on just reg radio stations. Sounds like a ground problem maybe with the radio/Cigerette lighter?
