Delphi NAV300


The Delphi Nav300 is a full-featured portable GPS unit that does everything from directing you to the store to playing MP3s. It's small enough to be unobtrusive in the car, and does a great job of getting you to your pre-defined destination, as well as...

Accurate navigation; lots of features; can find points of interest

Slow; extra features are useless; screen is too small; orphaned stylus

We're willing to cut the Nav300 a bit of slack due to its low price of just $399 USD, but it's still a flawed product.

Delphi NAV300


The well-equipped Delphi NAV300 comes with cool extras such as Zagat reviews and subscription-free live traffic info.

Offers text to speech. Optional subscription-free traffic function. Multisegment routing. Zagat Survey listings

Can't search POIs near destination or near specific address. Bluetooth phone interface doesn't sync your phone's contact list or call history. Separate traffic receiver and antenna

The Navigon-powered Delphi NAV300's feature set is almost identical to the Navigon 5100's. If you don't need the live traffic option but appreciate a Bluetooth phone interface, the NAV300 is a better choice. But if you need live traffic info and don't...

Delphi NAV300


Design 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...

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...

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.

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.

If you're looking for a moderately priced GPS unit that has basic navigation features then the Delphi Nav300 GPS might be the perfect GPS for you costing only $300.

Delphi NAV300 Portable GPS Navigation System Review


When portable GPS navigation systems first hit the market, they were slow, quirky, and in some instances, got you more lost with it than without it.  With better hardware and more accurate maps, today's GPS systems finally have what they…

Quick startup and intuitive interface ; Good accuracy and on the road performance ; Great visual indication of turns and upcoming exits ; Text to speech was loud and clear ; Built in Bluetooth Hands-Free kit ; ZAGAT makes finding a good place to eat...

Fluffy useless features like movie and MP3 player ; Number and letters could be larger to facilitate easier data entry ; A bag or case would be nice to protect it when exploring on foot

The NAV300 came with a huge list of features, and although the majority of them were useful, I found a few that weren’t.  First off, the inclusion of the MP3/Movie player I thought was rather silly, particularly because you can’t use this function...

Review: Delphi NAV300 GPS


I'm just back from a trip to Spain and I wish I had taken a GPS with me. The maps were horrible and the signs confusing. We spent a good amount of time lost, and try asking for directions when you're not fluent in the local dialect. While it's true...

My girlfriend and I get in the car. She mounts the NAV300 on the windshield, flips up the antenna and adjusts it easily. It takes about two minutes to find the satellite (consistently). When she starts the GPS the screen loads up. It's a sunny day and...
