Need proof? Mine will drown out the radio in my car with buzzing before it rings.
It's not your radio picking up the interference, it's the speakers buzzing when your phone rings. Same thing will happen with any speaker you are near when the phone rings
TV stations aren't on or near our freqencies either but harmonics from them have made certain channels in certain area's useless.
Look at the chart posted earlier. Actually TV frequencies are very very close to our radio's frequencys. In fact, broadcast channels 2-4 broadcast on 53 MHz to 72 MHz and our radios are just above the 72 MHz line. Broadcast TV channel 4 does cause some interference with our lower channels in some areas. Here's the link to the spectrun chart again.

All that being said, most radio problems that get blamed on "getting hit" are usually caused by poor installation or older equipment or mixing and matching crystals trying to save 3 bucks. Nearly all of which could be prevented by proper installation and proper maintence.
I couldn't agree more on this one. It seems some people will blame everything else for a crash instead of poor installation or "dumb thumbs".
