We all want foolproof navigation, full iPod control, built-in Bluetooth, and tons of customizable user controls in one single package. The only problem is that we drive minitrucks, and lack of dash space usually doesn’t allow for such newfangled technology.

Luckily, Sony’s new XNV-660BT deck features all of the above functions into the company’s smaller-than-average double-DIN unit. Measuring in at just 7.125x4x6.875 inches (w/h/d), this all-in-one head unit fit right into our 2000 Chevy S-10’s stock 1.5-DIN dash opening with only the slightest bit of trimming required.

The 6.1-inch touch-screen display is brilliant and easy to navigate in between audio sources, but it really comes to life while in the TomTom-powered nav program. One million miles of accurate maps have been preloaded, and the portable navigation module allows for easy updating, which is completely free for the first year. Audible turn-by-turn directions make usability even better here.

Now let’s talk music, since that’s what most of us are interested in when dropping a wad of cash on a new head unit. The 660BT’s 7-band equalizer, Listener Position, and Center Stage Optimizer settings would please any true audiophile, and media playback options are king with a front CD/DVD slot and rear USB 1-wire connectivity for iPod, iPhone, and most other USB-driven MP3 devices. Add satellite radio using a simple bus adaptor, and increase entertainment value exponentially.

Simply put, Sony’s double-DIN entertainment deck is a solid choice for those looking for more than just a pretty face. Get the features you really want in a single sleek, smart, and sophisticated unit.
