Harman Kardon GPS-500 Widescreen Portable GPS Navigator, MP3 Player, and Video Player

Turn-by-turn directions and navigation prompts appear as needed, even during music playback.

Enjoy your favorite music in your car--or on the couch. The unit supports MP3, AAC, and WMA audio formats.

The SD card slot supports up to 4GB, enough room for hours of video.

Granted, you don't get some top shelf features like Bluetooth integration, text-to-speech address announcements, or wireless traffic reports, but Harman Kardon has wisely stuck with basics and polished them into an experience that, apart from a few software problems we encountered on our pre-production model, doesn't fail to disappoint.

Navigation
The main purpose of any car GPS device is to take you reliably from point A to B. Here the GPS-500 performs nicely indeed, providing several options for finding your destination. To get going you can select either a street address, a specific point of interest such as a gas station or restaurant, a recent or saved destination, a postal code, or an intersection (if you're not sure of the exact address). To speed up text entry, the unit employs an intelligent auto-completion feature that displays only the letters that spell an item in its database. This greatly reduces the letters from which you have to choose to tell it where you want to go.

Multimedia
The GPS-500 strives to be much more than just another GPS device in a crowded market, and that's likely why Harman Kardon has polished the multimedia features of the device so well. With support for MP3 and WMA music files, the music player has a refreshingly intuitive user interface and good sound quality. It's a cinch to browse music on your SD card by artist, album, genre, playlist, and song. Another nice touch is that you can keep the music playing while the unit is in navigation mode.

Video playback is equally straightforward. The device recognizes WMV9 or MPEG-4 AVI video files and presents them in a scrolling list. Press a title and you're off in movie land, complete with smooth framerates and minimal jitters during high-action sequences. We did encounter a format incompatibility with an AVI file encoded in the DIVX format. Attempting to play the file freaked the GPS-500 out, and a hard reset was required. Harman Kardon is very clear about which file formats are supported, but many folks might inadvertantly attempt to play a DIVX-encoded AVI instead of an MPEG-4 AVI. Broader format support would be a welcome addition.

To ease some of the pain of getting your movies and TV shows into the right format for the GPS-500, Harman Kardon provides a brief guide for Windows Media Player users. Mac users will have to use third-party media encoders to prepare their videos for the GPS-500. Lastly, battery life when playing back videos was surprisingly good. After a two-hour movie the GPS-500 was only down to a 40 percent charge.

The only button you'll find on the device is the recessed power button on the top, right next to the SD card slot. The slot accepts cards with up to 4 GB of capacity. There's also a small jog wheel on the right side for volume and display brightness control. Below this dial you'll also find a mini-USB port that serves double duty for both charging and PC-to-device data transfers, as well as a standard 3.5-millimeter headphone jack. Meanwhile, you'll find a pinhole reset button on the bottom, as well as a hold switch on the left side for deactivating the touchscreen. Lastly, the back of the unit sports a small audio speaker and a port for an optional GPS signal booster antenna.

Setup and Interface
Setup is as easy as turning the device on, since it comes loaded with maps of the U.S. and Canada. On first bootup, choose from English, Spanish, or French language options for the spoken directions and interface menus.

Interacting with the GPS-500's touchscreen is delightfully intuitive and reliable; there's really no need for a stylus or navigation buttons, which simplifies things on the road. The division of the main interface into four main quadrants is a helpful touch, and it's refreshing to see manufacturers moving away from awkward icon-based menus. Instead of drilling down through lists of icons, all of the GPS-500's options are presented on simple, color-coded shapes. That said, we were a little puzzled by the use of the "Source" menu key, which takes the user back to the main menu from any point in the interface. It's a useful feature, but why not call this the "Home" button instead?

The screen itself is sharp and clear, offering great resolution and clarity in all driving conditions. The map screen is a sight to behold, offering delightfully crisp 3D images, as well as excellent responsiveness when zoomed and panned. Likewise, the interfaces for music and video playback are pleasantly uncluttered, responsive, and well thought-out. One problem in our unit, though, was the lack of a sleep mode. The device's screen will stay on at full illumination when it's left idle--even when running on battery power. There's also no sleep button on the device.

The GPS-500 provides audible commands for turns, which is very useful for anticipating upcoming maneuvers. As mentioned, though, the device does not provide text-to-speech capabilities for reading the names of locations or upcoming addresses.
