I want a hardware that I can control via roadrunner,

Some thread in the newbie section said I could use a gps reciever to recieve fm-radio stations,,,, ?
Iīm confused here, but I guess its about xm radio...

I want a usb fm reciever with RDS function, does it exist yet or still project?

No matter if I get a winTV, radioextreme or those fm mouses,..... if they have an antenna-in they will be connected to my carīs factory fitted antenna so I guess the reception will be equally good to each. Only a matter of build quality so the sound quality would differ a bit right?

Someone said these were able to have a adapter to the small wire/antenna comming out from the stick and that way connect it to the car antenna, that way this little thing must be quite good or?
