Your Road Map to the Perfect External Car Navigator

Buying an external car navigator can make your drives much smoother. These devices help you find your way without relying on your phone. This guide will help you choose the best one for your needs.

Key Features to Look For

When shopping, look for features that make navigation easy and safe. A good navigator does more than just show you where to turn.

Screen Size and Clarity

Size Matters: Choose a screen size that fits well on your dashboard. Bigger screens (like 5 or 7 inches) are easier to see at a glance.
Brightness: The screen must be bright enough to read in direct sunlight. Good contrast is also important.

Map Quality and Updates

Up-to-Date Maps: Ensure the maps are current. Outdated maps lead to wrong turns.
Free Updates: Check if the manufacturer offers free map updates. Some require yearly subscriptions, which adds to the cost.

Voice Guidance and Traffic Alerts

Clear Voice Prompts: Loud, clear voice directions help you keep your eyes on the road.
Real-Time Traffic: Many modern units receive live traffic data. This feature helps you avoid traffic jams and construction delays.

Mounting and Power

Secure Mount: A strong suction cup or adhesive mount keeps the device steady. Shaky screens distract drivers.
Power Source: Most plug into your car’s cigarette lighter socket. Check the cable length to ensure it reaches easily.

Important Materials and Durability

The materials used determine how long your navigator lasts. You want something that handles heat and vibration well.

Casing: Look for durable plastic casings. These resist cracking if they get bumped.
Screen Protection: A tough screen surface resists scratches from cleaning or accidental touches.

Factors That Improve or Reduce Quality

Certain aspects significantly boost or hurt the navigation experience.

Quality Boosters:

Faster Processors: A quick processor means maps load faster. Pinch-to-zoom should feel smooth, not laggy.
Lane Assist: This feature shows you exactly which lane to be in before a complex junction. This feature greatly reduces stress.

Quality Reducers:

Slow Re-routing: If the device takes too long to calculate a new route after a missed turn, it frustrates the user.
Poor Antenna Reception: A weak GPS antenna loses signal easily, especially near tall buildings or in tunnels.

User Experience and Use Cases

How you plan to use the navigator dictates the best choice.

For Daily Commuters:

If you drive the same route daily, a navigator with excellent real-time traffic data is essential. It helps you save time finding faster back roads.

For Long Road Trips:

For long trips, battery life (if you use it outside the car) and offline map capabilities are vital. You do not want to lose navigation in areas with no cell service.

Ease of Use:

The menu system should be intuitive. You should be able to enter a destination quickly and safely. Complex menus waste time while you are driving.

Frequently Asked Questions (FAQ)

Q: Do external navigators still work if I lose my cell signal?

A: Yes, most external navigators use built-in GPS chips. They only need a signal to download traffic updates, not for basic map navigation.

Q: Can I use an external navigator in a rental car?

A: Absolutely. You can easily move them between vehicles using their suction cup mounts. This makes them very flexible.

Q: How often do I need to update the maps?

A: Map updates are recommended at least once a year. New roads and construction zones appear frequently, so keeping them current is important for accuracy.

Q: Is a built-in car system better than an external one?

A: External navigators often have newer software and simpler interfaces. Built-in systems can be slow to update and sometimes cost a lot to upgrade later.

Q: What is “lane assist,” and why do I need it?

A: Lane assist shows you a picture or graphic of the highway signs. This helps you choose the correct lane well before you reach the exit ramp.

Q: Will a large screen drain my car battery if I use it without the engine running?

A: Yes, any powered device will drain the battery. Most units are designed to draw very little power when plugged into the 12V socket.

Q: Should I mount it on the windshield or the dashboard?

A: Check your local laws. Many places restrict mounting anything on the windshield that blocks the driver’s view. A dashboard mount is often safer and legal.

Q: What is the difference between Garmin and TomTom?

A: Garmin and TomTom are the two biggest brands. They both offer reliable navigation, but their map styles and subscription costs for traffic services can differ slightly.

Q: Can I connect my navigator to my car’s Bluetooth?

A: Many modern external units can connect via Bluetooth. This allows the voice directions to play through your car’s speakers, which makes them much louder and clearer.

Q: How long do these devices usually last?

A: With proper care, a quality external navigator should last three to five years before needing replacement due to outdated software or hardware failure.
