Harman Kardon makes the "radio", but who makes the components in the radio ?
 

Note: Found this while looking around the internet for stereo upgrade options.

Atmel makes the radio chipsets used to receive and process the radio signals . . .

See page 13 of this atmel brochure for their line of IC's used for car stereos . . . Recognize anything in the photo?

Or how about this brochure for atmel's broadcast radio solutions . . . recognize the layout and image on the radio NAV?
