The manufacturer's suggested retail prices (MSRP) for the individual CX-DV700 and LCD monitor console are $799.99 and $1199.99, respectively. The new packaged system, designated as model PKG-DVD1, has an MSRP of $1599.99, which is $400.00 less than the combined individual suggested retail prices. "Today's wide range of mobile entertainment products can be overwhelming to consumers looking to retrofit their vehicles with the latest equipment," says Rob Lopez, national marketing manager for Panasonic car audio products. "Panasonic has put this inclusive package together to help make that choice more convenient. The PKG-DVD1 offers consumers an exceptional entertainment system at an outstanding value." The compact, DIN-sized CX-DV700 offers flexible installation options and can easily fit in the dash, in the trunk or under the seat. The DVD player is controlled by an IR remote. The CX-DV700 features a built-in MPEG2 video decoder, high-precision 96kHz/24-bit D/A converter, automatic disc loading, anti-shock memory and floating mechanism. Outputs include video-out (RCA), audio-out (RCA x 2ch), digital audio-out (optical), and an RM data terminal for remote control convenience. The CX-DV700 also plays CDs. The CY-VMX6800 is a ceiling-mount console with a drop-down, 6.8-inch color TFT active matrix LCD monitor. For optimum visibility, the high-definition, 269,568-pixel panel features an anti-glare coating and manual adjustment, tilting in 4 steps and swiveling up to 30 degrees left and right. Two sets of audio/video inputs (RCA) allow connection of a second video source such as a game unit. The console also features built-in reading lights. Passengers in both the front and rear seats can enjoy independent audio sources. An infrared transmitter and two included sets of wireless headphones allow private listening, so the kids in the back seat can enjoy their favorite DVD movie without disturbing the driver.
