GPS

Greetings Car Tech fans and welcome back to CNET Roadside Assistance. Listeners of the podcast formerly known as Car Tech Live will no doubt remember that we used to devote an entire segment to answering user e-mails. Well, we're back, only in a less auditory format. So if you've got a car tech question you'd like to have answered, and you may find the answer to your query right here on the Car Tech Blog.

And now, let's get to the questions. "Twoheadedboy8" asks:

Sen. Al Franken (D-Minn.) wants the Justice Department to hand over any information it might have about law enforcement agencies getting their hands on location data from cell phone companies.

Earlier in the year, the U.S. Supreme Court ruled in a case, United States v. Jones, that law enforcement agencies needed to first obtain warrants before using GPS devices to track people. In that case, the justices said law enforcement could not install tracking devices without a warrant, because that fell into the definition of a "search."

But in a letter yesterday to Attorney General Eric Holder (… Read more

Recently I asked if it still made sense to buy a GPS, what with smartphones more than capable of navigating folks from point A to point B.

Many readers commented that, yep, their phone gets the job done. Of course, there's one small challenge to using it for this purpose: smartphones don't come with car mounts. You need a way to position it at eye level so you can see your maps.

There are countless universal-mount options out there, many of which use suction cups to adhere to your windshield and gooseneck arms to hold the phone. Not … Read more

In the face of a few solid free navigation apps for the iPhone, such as Bing or MapQuest, MotionX GPS Drive would seem to have trouble justifying its price, even at only 99 cents. But it has proven a popular enough navigation app that Pioneer integrated it with the AppRadio head unit.

Two features of MotionX GPS Drive give it an edge over the free apps, its destination search capabilities and the ability to preload maps. MotionX GPS Drive is a connected navigation app, meaning it relies on an iPhone's data connection to get its maps. However, it is … Read more

We're all aware of that corner of the market filled with products targeted at elderly users: mobile phones with limited functionality designed not to confuse, remote controls with huge buttons that are easy to read, and landline phones like the FotoDialer. Could the next product in this niche be a GPS navigation system for your grandma? A £12 million grant from the U.K. government is pushing in that direction.

Newcastle University Prof. Phil Blythe, who is heading up the team researching the project, cites waning eyesight, nervousness, and decreased confidence as issues for older drivers. The navigation … Read more

There are any number of apps that can help you pinpoint a friend's location, but they all have one thing in common: they require that friend to have the same app installed and running, and usually to sign up with YAS (Yet Another Service).

And don't forget, it's a two-way street: you have to run the app yourself, and leave it running all the time -- a pretty big drain on the ol' smartphone battery.

Enter Space-time for iOS, a clever cross-platform locator app that runs only when you need it to and requires no installation or … Read more

Garmin's GPS devices have reached a significant milestone.

The company announced today that it has now sold 100 million Garmin devices worldwide since its founding in 1989. The first Garmin device was sold in 1991, the company said, and took six years to reach its one-millionth sale. By 2007, it had sold 25 million devices. Now, just five years later, it has tripled that figure.

Based on the data provided by Garmin, sales are accelerating. In fact, Garmin acknowledged that much in a separate earnings release today, saying that it sold 2.7 million GPS units during the first … Read more

With so many navigation apps available, many for free, it may be difficult to imagine paying for one. But ALK Technologies makes a reasonable case for its CoPilot Live Premium app. Its most compelling feature are the full set of maps it includes, making it possible to navigate without a data connection.

Most people using a smartphone for navigation will be doing 95 percent of their driving in an area with data coverage. But the most critical times for a good navigation app come out on back roads, far away from cell towers. Likewise, high data roaming charges in foreign … Read more

Getting (or sending) turn-by-turn driving directions is now as simple as clicking a link in a text message or e-mail with Telenav's new Scout navigation Web app and your phone's HTML5 browser. OK, so there are more steps than just that one, but it's still a remarkably simple process.

Simply visit Scout.me with any browser and search the city of your choice for something to do, somewhere to eat, or somewhere to sleep. Destinations are organized into the main categories of Things to do, Food and Drink, Events, and Places to stay, with multiple subcategories for … Read more
