Your car's GPS can do more than just give you directions. For example, you can download and install fun and free new vehicle icons. Tired of your GPS's voice? Download and install some celebrity voices. You may also use your GPS to find the best gas prices.

Find the Best Gas Prices

'Cheap' and 'gas' don't always belong in the same sentence, but we all want to find the lowest available prices for the stuff. You can consult websites that consolidate and compare gas prices, but you'd have to do this in advance of your trip or during a stop. Instead, use your car's GPS to find the cheapest gas prices along your route as you're traveling.

For example, TomTom's Fuel Prices feature helps you find the lowest gas prices by identifying and ranking stations by price and location. It then provides turn-by-turn driving directions to the gas station with the best price. You will need a compatible TomTom 'GO' model in-car GPS and a yearly subscription to the TomTom Fuel Prices service to use this feature.

Keep Tabs on Family Members and Pets

When you're concerned with the whereabouts of family members such as kids and elderly parents, consider using one of the many apps out there that use GPS to locate them. Glympse, bsafe, Cabin and Life 360 are just a few to try.

For wandering Fidos, GPS-based trackers are now available that attach to dog collars and enable real-time tracking. You can even set up a geofence—a boundary that triggers an alarm if your pet goes outside of it.

Dude, Where's My Car?

Likewise, you can add a tracker to (and geofence around) your car. This GPS transmitter will tell you where your car is in the event of theft—or if you've forgotten where you parked it.

Get Some Grub

Google Maps can show you restaurants in your area (which it determines from the GPS signal of your computer, phone, or another device), sortable by rating, price, cuisine, hours, and more. Many listings now offer ordering through delivery services such as GrubHub and Chowhound.

Find a Parking Spot

Gta underground game setup free download for pc. Google's navigation app, Waze, can tell you the location of parking lots near your destination. You can even see how long getting from a given lot to your destination will take.

Customize Your System

You're not stuck with the default icons and voices in GPS navigation systems. Most offer much more interesting car icons than the few that appear within your unit's stock menu. In fact, you don't need to 'drive' a car on the screen at all. How about a fire truck, football, tank, police car, motorcycle, or stock car? Sound like fun? Download and install free new GPS icons is easy and fast.

You're not stuck with the nice but generic voice that tells you where to go, either. Most systems and apps come with alternative voices built in. In some cases, though, you can download and install amusing new text-to-speech voices that will impress your friends, miff your significant other (some alternative voices are downright sultry), make you laugh, or just provide digital companionship as you find your way through the world.

As a publicity stunt, things don't get much cooler than having a big-name actor give an in-character performance in your car. That's what happening with Arnold Schwarzenegger, who is lending his voice to the mobile crowd-sourced traffic and navigation app Waze to promote the new Terminator movie.

But the former governor of California is far from the first big celeb or major fictional character to get into the directions-giving game. In fact, he's not even the first one to do it for Waze—that was comedian Kevin Hart, who provided turn-by-turn commentary for the app in 2013 (to pimp his flick with Ice Cube, Ride Along.)

Using celebrity/character voices in navigation systems goes back almost a decade, and features some of the biggest names in the world. Check out the slideshow for our collection of the greatest and geekiest. Most are still available for purchase (or free), particularly if you have a compatible Garmin or TomTom navigation system (check compatibility before you buy). How this hasn't become a thing for Google and Apple Maps on phones yet, I don't know. Maybe Drake can record one for Apple soon.

• 1Darth Vader and Yoda

  No two characters better represent the dreaded Sith and the heroic Jedi than these two. Recorded for TomTom in 2010, they're still available there (both for $12.95), and for Garmin ($9.95 each). Also available: C3PO and Han Solo! (I want to believe that's really Harrison Ford.)

• 2The Simpsons

  Homer and Marge and Mr. Burns are all available as separate voices on Garmin ($10.99 each) or TomTom ($12.95 each) so that when you miss a destination, you get that highly appropriate 'D'OH!'

• 3Mr. T

  We seriously pity the fool who doesn't have this excellent voice on their GPS. He's available for $12.95 on TomTom's PLUS Services

• 4Looney Tunes

  Bugs Bunny, Daffy Duck, Sylvester the Cat, Yosemite Sam.. legends all. And all legends you can have tell you were to go on a TomTom for $12.95 each. Little bits of the classic Looney Tunes themes makes it all the sweeter to get to Albuquerque, Doc.

• 5K.I.T.T.

  You might think of actor William Daniels as the guy from Boy Meets World. But for years, he was also a TV doctor, and before that, he was a car. Specifically, the sarcastic voice to the talking vehicle on Knight Rider. Now, he can sarcastically tell you what exit to take (if you've got a TomTom and $12.95).

• 6Wallace & Gromit

  The greatest Claymation stars of all time (if you don't believe me, go watch The Wrong Trousers) lend their voices to GPS. Well, Wallace does, as Gromit's not much of a talker. They're a bargain on Garmin for $8.99, but still $12.95 at TomTom.

• 7GlaDOS

  It's not official, but there's a voice out there perfectly mimicking that of GlaDOS, the homicidal AI from the Portal video games. Luckily, this GPS voice, created by a user on Reddit, apparently doesn't make you drive off a bridge like the real one. This is a free download for Garmin and TomTom units.. if you can find a working link. Oh, I found one, but it'll cost you $9.97.

• 8Arnold—The Govenator

  Arnold's already on your GPS? Sort of. There's a huge collection of NSFW, non-politically correct, celeb and character parody voices for GPS to be found at Pig Tones. Arnold is just one of them. Typical voices include Pagoda (a Yoda pastiche), Capt. Jack, a filthy-mouthed drill sergeant, Beavis & Butthead, Sean Connery, Gollum, Obama, Dubya, and yes, GlaDOS. Also: Jesus with appropriately heavenly echo. Every voice they have is $9.97 for TomTom or Garmin units.
