FM radio Makes noises Only when driving

My tundra radio makes noise on the FM band only when driving. Very strange. AM is perfect and so is HD and XM channels. What could it be????

 

And thank you for having me on this great forum. By mistake i found it on a search engine.

 

Yes while idling it does not make any noise or static. Only for FM, AM and XM are fine. So strange, thanks for the help.

 

WELCOME

 

Thanks for the help Ron. It is possible the technician hit something when checking for noises on the left hand side of the steering wheel. Perhaps when he re-assembled he hit something. But i still cannot understand why only FM and Not AM and XM radio. I have sent a message to Toyota as well maybe they can figure something out.
