More than 25% of US consumers own MP3 player equipment for their vehicles, according to Consumer Electronics Association. This may seem like a far cry from the majority (97%) who own the long time standard AM/FM radio, but the new study shows digital audio alternatives have gained a significant foothold in the automotive electronics market. MP3 players, cell phones, mobile and portable video navigation and factory-installed autosound equipment contributed to the $6 bln (27%) growth of mobile technologies in 2005. CEA estimates that $27 bln worth of mobile electronics products was shipped in 2005 and more than $30 bln will be shipped in 2006.
