Complaints aside, the unit routes and reroutes quickly. The GPS is also spot-on, knowing exactly where you are on the road and prompting you to turn in a timely manner. Voice guidance isn't as frequent as on some other units, but if you're like me, too many prompts are an annoyance you'll be happy to be rid of. If you feel like you need more guidance, you can always easily glance down at the screen to see the next direction on display. Another welcome feature is a one-button touch to view your complete route.
Additional Features
The NVG-670W gets its "multimedia" designation from the multitude of listening and viewing options. The main menu is easy to pull up from a hard button on the side of the screen. From there, soft buttons will bring up the various other functions. The old standby, AM/FM radio, features 12 preset stations per band. With the CD slot, you can listen to various CD formats, MP3s, WMAs, and view JPEGs.
If you correctly installed the safety parking brake wire, you can only watch DVDs up front while parked, which is something we highly recommend. Tapping the touchscreen brings up the soft controls for DVD viewing, though you can also opt to use one of the three remotes! If you have a 5.1 speaker setup, the unit also outputs for surround sound.
As I mentioned before, there may be a downside to paying so little for all of the NVG-670W's features. For instance, my iPod synced up perfectly the first time I tried it; the interface let me access songs based on artist, album, playlist, etc. But a few days later, it refused to connect. I tried resetting the unit and testing different iPods to no effect. Fortunately, Valor provides a one-year limited warranty, but sending a product in for repair or replacement is always a hassle.
Hands-free calling works with just about any Bluetooth-capable phone, but the full functionality of the interface, such as having caller ID pop up on the screen when a call comes in or accessing your phone book via the unit only works with a select number of phones. This didn't include the Motorola SLVR or Samsung Blackjack I tested it with. However, the NVG-760W did sync reliably with both phones and make and receive calls clearly. That's the most important point and it's great that Bluetooth came included with the Valor, rather than being a separate product you need to purchase for another $100 or more, as with some competitors.
Conclusion
At the time of this writing I did a quick search and found the NVG-760W for under $1,000 at a variety of sellers. That's not bad for a unit that does so much. I have complaints about the touchscreen sensitivity and, of course, wonder about long-term reliability, especially since the iPod function failed. When you consider the price point, though, you have to allow a few faults. If you're on a limited budget but still want all the features that the NVG-760W offers, you've found what you're looking for.
