One impressive thing about Scion brand is that they are one of the leaders in audio systems. For a budget car line their audio systems feature Pioneer and Alpine headunits, Pioneer speakers and amps, full iPod integration, they play most popular file formats on CD-ROM (WMA, MP3, and AAC files), have steering wheel mounted audio controls, and satellite radio capability. They even give you both iPod cable and an auxiliary jack cable, at no charge!
Some glaring omissions have been they are all single disc players, lack bluetooth connection (a stand alone option now), and they do not offer HD radio and USB connection capability. As they are ready to introduce the 2010 model in late April-early May, they have upgraded and updated their audio systems.
From 2007-2009, the Scion models used 3 different units. Base Pioneer, Premium Pioneer (RCA pre-amp outs), and Alpine Navigation units. Starting the 2010 model year, it looks like they will be going with 2 units – base Pioneer and Premium Alpine (Nav, USB, and HD radio Ready), but we are still not sure if they are multi-disc changer units.
