Over a year ago I got a new radio for my daily driver, and an XM subscription. I have yet to tune in to an AM or FM station, honestly I could do without an antenna. I have only played two CD's in that time, I could do without a CD player too.
For my 48, that will one day be a daily driver, I had planned on the hidden antenna in question here, but I can now see I won't need one. I can't stand to listen to the commercials on a regular radio any more, I'm spoiled by the satellite radio. I also can listen to my iPod through my radio, as if there are not enough choices on the satellite radio.
Something to consider...
