Pioneer loosed details on its AVIC-X3, along comes word that we can also expect an AVIC-N4 in the not-too-distant future. This single-DIN unit boasts a motorized, flip-out seven-inch touchscreen, optional iPod / Bluetooth compatibility, CD or DVD playback, XM / XM NavTraffic-readiness, and a Tele Atlas database for routing you around. Regrettably, the lack of an internal HDD means that you'll be forced to insert the map DVDs in order to access guidance, but users can feel free to toss in discs with MP3, WMA, AAC, or DivX files when the drive is clear. Furthermore, the unit can even accept tunes streamed in wirelessly from a mobile handset when utilizing the CD-BTB200 adapter, as it understands both A2DP and AVRCP protocols. So, now that you've found a satisfactory replacement for that aging factory head-unit, you've only got to scrounge up $1,600 to make the swap.
