Standalone GPS or cell phone?

I've got a Garmin GPS for my car. It's small enough to slip in my pocket, as well. And my cell phone wil tell me how to get where I'm going for a daily fee to Verizon; I haven't tried it yet.

Consumer Reports has some thoughts on the choice between a dedicated GPS and a phone.

• Smart phones are an increasingly popular navigation option, especially among models that come with turn-by-turn guidance built in. Other phones require purchase of a downloadable navigation app or a service subscription. In our tests, we have found that the best navigation applications are made by well-known GPS companies like Navigon, TomTom, and Magellan. These apps look and function much like a standalone GPS unit.

• Virtually any new cell phone is now capable of giving directions, whether it's smart or otherwise. Cell-phone providers, such as ATT and Verizon, offer turn-by-turn directions for a fee, usually about $10 per month or $3 per day. This form of navigation aid is handy for a vacation or if you only need directions occasionally.

• If you choose to go with a phone for guidance, keep in mind that a phone with a large screen will be easier to read and use on the go, and it can come closest to the performance of a portable GPS unit. But with any phone, you'll have to buy a mount and car charger separately, which can add another $50 or so. A good navigation app adds another $50, making the combined cost about as much as a dedicated device. And if you opt for a subscription plan, instead of a downloaded application, the monthly fee can quickly add up to more than the cost of a basic GPS in just a year.
