Imagine this: You're taking a drive, your GPS navigator is telling you to "turn left on Main Street" and then, just before you reach your destination, you think to yourself, "Gee, I wish I could make a quick phone call with it."

Now, you can. Garmin's Nuvifone G60 ($299 with a two-year contract from AT&T) is the first GPS navigator that doubles as a cell phone and Web browser. Unlike most cell phones that include a GPS feature, the Nuvifone offers integrated, audible turn-by-turn directions.

Until recently, you couldn't buy a cell phone that also gave you great audio directions. Google changed that with the introduction of Droid, a new $199 phone from Motorola and Verizon, coming later this week.

But the mapping feature is available only on Droid, not yet on older Android phones or on rivals such as the iPhone. So let's take a look at the Nuvifone.

• Talk and drive. The biggest selling point for the Nuvifone is that it doubles as a hands-free car speaker. You can talk on the phone and get mapping directions at the same time.

Both Garmin and rival TomTom have other hands-free GPS units that let you do this by connecting your Bluetooth phone to the GPS device. If you talk, the audio directions come to an abrupt stop. The screen still shows you the mapping, however.

• The phone. The Nuvifone is roughly the size of an iPhone, with a slightly smaller screen. The virtual keyboard might throw you off, though, because it's in alphabetical order, instead of the usual qwerty.

• Searching. GPS units are great for looking up nearby gas stations, restaurants and other businesses, because they use satellites to figure out your location. With the Nuvifone, results are listed with directions and a phone link. For an extra $5.99 a month, you can search for real-time traffic and access other information, such as nearby movie listings.

• Where's my car? How many times have you gone to the shopping mall or a sporting event and found yourself lost in a sea of cars trying to find your own? With the Nuvifone, you take the device with you and when you return to the parking lot, open the menu and look for "Last Position."

The Nuvifone also has a Web browser, Wi-Fi capability and 5-megapixel camera. The geo-location feature works really well with photos; they're tagged to let you know where they've been snapped.

Bottom line: Garmin makes great GPS units, but at $299 plus service fees, a good GPS with an inferior phone is probably worth passing over.
