The AVN5510 offers a couple of very useful options for viewing the navigation route details before setting out. Its Turn List provides an itemized readout of all the stages of the journey, while its Route Preview function gives an onscreen run through.
For digital audio playback, the AVN5510 supports regular CDDA discs as well as discs encoded in MP3 and WMA formats. Navigating digital audio libraries is made very easy by the intuitive touch screen menus that show folder and file information in a clear format.
Navigating DVD menus on the AVN5510 can be laborious, but with a video playing, controls such as play, search, and pause are helpfully available at a touch of the screen. The 7-inch screen delivers rich video reproduction, especially in the wide-screen display configuration.
To maximize screen area, the AVN5510's two disc slots are hidden behind its roll-down faceplate, which opens at the touch of a button. The lower DVD slot can be used either for the GPS navigation DVD-ROM or to play DVD videos.
The AVN5510 provides turn-by-turn, voice-guided navigation. Customization options for the navigation system are impressive, with options for auto-reroute, intersection guidance, and building-shape display for streets in metropolitan areas.
