The car audio & electronics aftermarket saw a 14 percent drop in dollar volume in 2012, said the NPD Group.
Sales to consumers for car audio, video and fixed navigation fell to $1.8 billion (excluding portable navigation and portable video).
In-dash head units fell 9 percent to $328.7 million, said NPD.
As noted last year by NPD’s Ben Arnold, consumers appear to be bringing their own source material into the car but they want the improved sound of speakers and amplifiers.
