surprised they don't use hd radios....no i'm not.
It's funny you mention this...
My wife bought a '16 Toyota RAV4 Hybrid in July. Driving home behind her one day, she calls and says that her radio sounds terrible. The volume keeps changing, and she wants me to turn off the auto volume adjustment feature. I turned it off, but noticed the volume kept going up and down, no matter if I was on or off the throttle, going fast or slow. Then I noticed the HD symbol was going on and off. When it was on, it sounded very clear and loud. When it was off, it sounded muddy and quiet. I turned off the HD, and the volume and sound quality stay consistent, if not as good as when HD is locked in.
About a month later, I bought my '16 Colorado. I noticed the sound quality and volume levels constantly changing, and I began looking for the setting to turn off the HD. I quickly realized that it wasn't in fact HD. I'm glad I'm not the only one that thinks the FM is crap in this truck. It sounds fine using my iPod, so I knew it wasn't the speakers. When I bought a W/T with the 4" display, I was told that the LT with the larger screen had more problems with the radio, so I didn't feel too bad about buying the cheaper truck. I guess it would be nice to have the Sirius/XM, though.
