2009 tech radio making strange noise..

[2009genesis4.6]

Hey guys I've owned my 2009 4.6 with the tech pack for over three months now and twice when I have started the car the radio turns on and is in fm, there is sound but it sounds all scrambled. It does not do it for long but I had a chance to change over to cd and it sounded fine. It did it one when I first got it then another time over two months later. I turned the stereo on and off twice then it was fine. Is this somthing I should be concerned about? Or is it just a software glitch that may happen every 4 to 6 months. Any info would be great, thanks.

Dont worry... its just Mariah Carey screaching another one of her 'songs' out.

I've had my '11 almost four years and it's done that a few times. Always has corrected itself, though.
