Valor NVG-670W Review

You, like many other millions of consumers worldwide, want a product that features plenty of options and functions with the lowest cost possible. It’s completely understandable because it is the typical consumer mindset. Double DIN navigation with 6.5” LCD monitor typically sell at around $750 to more than $1000 per unit. But look take a look at the Valor NVG-670W, a feature packed in-dash navigation with plenty of “bang” and a lot less bucks than more popular navigation units.

The first thing you’ll notice is the 6.5” LCD touchscreen display on the front panel. It is centered but bordered by a row of buttons on each side of the screen. This configuration does not make the unit appear to have an off-center installation like the Pioneer AVIC-D3. In addition, the DVD slot input is actually hidden behind the screen which gives it an even cleaner installation look.

The navigation unit is built-in but requires the included DVD media for it to function but still leaves the SD Card port and the USB input completely free for your audio or video uses. It is also capable of navigating in 2 dimensional or 3 dimensional course-plotting and features over 11 million points of interests (POI) and instructs drivers with vocal guidance.

Its multimedia features include the capability for it to play DVD±R/RW, CD-DA, SVCD, VCD, CD, CD-R, CD-RW, AVI, XviD, JPEG, MPEG1, MPEG2, MPEG4, MP3, and WMA in NTSC or PAL color format. Evidently, the Valor NVG-670W does not leave anything out and could play virtually any media format the world has to offer. The in dash receiver is also capable of dual zone audio output, giving the rear seat passengers the ability to listen to a different media than the front seat passengers. It also features a 24-Bit 192 kHz DAC with high and low pass crossover filters, which gives significant enhancement to the sound quality it puts out. You’ll also be able to expand with its front, rear, center, and subwoofer 2.5V preamp outputs, optional Sirius or XM Satellite Radio, and iPod capabilities. It even includes an iPod adapter and also built-in Bluetooth that will allow you to speak wirelessly through your existing car audio system, providing you with a safer way to communicate while on the road.

It is with no doubt that the Valor NVG-670W is a product to be reckoned with, especially true with its plethora of features and multimedia functions, built-in Bluetooth technology, integrated navigation unit, and a large 6.5” LCD touchscreen display. All this can be yours for less than $700!

Harman Kardon GPS-510 Review

Harman Kardon is of course known for its quality and reliability, offering you only the best in what high-end technology has to offer. To answer the increasing demand for GPS Navigation devices, Harman Kardon has answered with the GPS-510, an incredibly thin navigation unit capable of audio and video playback.

Pros
The interface is incredibly easy to use and is really easy to see. It does not make driving and navigating a dangerous task but instead renders it quite enjoyable with the bright and high-contrast 4" LCD touchscreen. In addition, the processing capability of the unit is extremely fast-eliminating the irritating nuisance of sluggish navigation. It has quick refresh rate and contains over 12 million points of interests.
The GPS-510 is incredibly thin, with a small width of less than ¾" thick. Only a few others on the market have this same thickness, but not as stylish and feature-packed as this one.

The navigation component of the unit is built-in and is also capable of receiving up to 16 different GPS satellite signals. Along with that, it could also receive live traffic information transmission in the area that you are driving. It also gives you an estimated time of arrival as well as time remaining until reaching destination. The colors on the map look great and truly characterize the navigation aspect of the unit to be 'high-tech'. It has the look and the feel of a truly high-quality portable navigation device.

The Harman Kardon GPS-510 also has great media playback capabilities, capable of playing AAC, MP3, and WMA audio files as well as WMV and MPEG4 video files. The unit could display album artwork and has familiar playback controls that are commonly used in media players.

reliability, offering you only the best in what high-end technology has to offer. To answer the increasing demand for GPS Navigation devices, Harman Kardon has answered with the GPS-510, an incredibly thin navigation unit capable of audio and video playback.

Cons
The fact that it has no built-in hard drive could be troublesome to many. However, the SD Card input supports up to 4GB, it may be cumbersome to switch in and out the SD Card. Though the manufacturer provides a USB connection, there really is no purpose for that unless you use the SD Card.

With all these great features, it's rather odd that the unit does not have HD or Satellite radio capabilities. Though the video playback feature is great, it's highly doubtful that anyone would be using video playback on a navigation device.
Another negative aspect is the price. The unit is selling at around $420 - $460. Unless you could get a good deal on the unit, you may be able to find other similarly featured portable GPS navigation units for cheaper.
