FM radio Reception bad

the one cd in dash radio im my 2010 access cab, prerunner, TRD sport sounds fantastic when playing cd's or ipod....fm is a different story. I can't determine if it's a reception issue or if the tuner (headunit) is bad. If the truck is parked and fm radio is selected...the sound is good....if I am moving (driving)...the sound gets distorted when music is playing but seems to be ok when the radio announcer is speaking.....any clue whats causing this?

 

When I go to the dealership next week to pick up the license plates I will have a service tech look into my reception issue. By the way, does anyone know who manufactures the non-jbl radios?...(I assume mine is non-jbl) just curious to know if they are Pioneer, etc....

 

might be a panasonic radio, at least mine was.

 

Bumping this old thread.

The FM radio reception in my 2009 was fine until a few weeks ago. Now I barely get any stations to come in. Only a few of the strongest stations come in and even they have a bit of static. I checked my antennae and it's screwed in tight and doesn't seem like it has any issues. Anyone else have this issue?
