The Good The Delphi NAV300 GPS device adds integrated Bluetooth for hands-free calling and text-to-speech functionality. The compact device also has multimedia features, and Delphi's optional traffic kit includes a lifetime subscription to Clear Channel's traffic service.
The Bad The Bluetooth integration is limited, due to a small number of compatible cell phones, and route recalculations weren't accurate. You can't use the music and navigation features at the same time.
The Bottom Line Though the Delphi NAV300 GPS navigator may look appealing with its affordable price tag and integrated Bluetooth and text-to-speech functionality, real-world tests show some pretty ugly results.
When we reviewed the Delphi NAV200 last year, we gave it props for being a good value and offering accurate directions. Now, the company has come out with a step-up model, the Delphi NAV300, and once again, we're impressed with how much the system offers for its $399.99 price tag, including Bluetooth integration and text-to-speech functionality. But the admiration stopped once we took it out for a test drive. The text-to-speech directions aren't as smooth as other GPS devices we've tested, and the number of compatible phones is so limited that it almost makes the Bluetooth feature worthless. We were also given inaccurate directions on a couple of occasions. You'll get much better performance from the similarly priced and featured Mio C520.
The Delphi NAV300 sports a design that's slightly revamped over its predecessor's. The overall shape is the same, but it's slightly more narrow and heavier at 4.6 inches wide by 3.1 inches tall by 1.1 inches deep and 7.6 ounces, compared to NAV200's 5.3 by 3.2 by 1 inches and 6.7 ounces. The system also retains the flip-up patch antenna on the back, rather than integrating the receiver into the device. We much prefer the latter, since it looks neater and you don't have to worry about lifting the antenna every time, but it's certainly not a deal-breaker. The Delphi NAV300 is still a compact and ultraportable unit, so you should have no problems transporting it between vehicles.
On front of the device, you have a 3.5-inch, 320x240-pixel-resolution touch screen. The display has an antiglare coating, but we found that the map colors slightly washed out when viewing in bright sunlight. The touch screen is responsive, but once again, we found the virtual keyboard to be rather cramped. And while Delphi includes a stylus in the box, there is nowhere to stow it in on the device itself--a big pain that guarantees you'll misplace the stylus at some point. The NAV200 had a stylus holder, so we're not sure why the company decided to omit it this time.
