The onslaught of new car stereos continues on the first day of action here at CES with another trio of single-disc receivers from Panasonic. The CQ-RX400U, CQ-RX200U and CQ-RX100U all come with front-mounted auxiliary input jacks for connecting digital audio players, while the top-of-the-range CQ-RX400U features a USB 2.0 port for playback of audio from iPods, flash drives, and other generic mass storage devices. The CQ-RX400U and CQ-RX200U can be connected to Panasonic's external module for XM/ Sirius Satellite radio; and Bluetooth hands-free phone calling. All three devices feature a 4 x 50W (max) amp and a 3-band equalizer. The CQ-RX400U will drop in February with a price of around $150, while the CQ-RX200U and CQ-RX100U arrive later this month priced $120 and $100, respectively.
