The most common and reliable way to get maps on your car's screen is by connecting your smartphone using Apple CarPlay or Android Auto. These systems mirror approved navigation apps from your phone onto the car's display, providing a familiar, updated interface. If your car lacks this technology, you might use the built-in navigation system, a dedicated GPS unit, or a simple phone mount. Apple CarPlay and Android Auto have become the industry standard for new vehicles. They work by projecting a simplified version of your phone's interface onto the car's screen. You control it via touchscreen, voice commands, or physical knobs in your car. The key advantage is that you use the data and real-time traffic updates from your phone, so the maps are always current. Wired connection is most universal, but wireless connectivity is becoming more common in newer models. Your car's built-in navigation system is another option. These are integrated directly into the vehicle's infotainment system. While often featuring high-resolution screens and integration with other car functions, they can have significant drawbacks. Map updates are frequently not free and require a dealership visit or a complicated download process, meaning your maps can become outdated. Some manufacturers also charge a subscription fee for real-time traffic data after an initial trial period. For older cars without a modern screen, a dedicated GPS device from brands like Garmin or TomTom is a straightforward solution. These devices attach to your windshield or dash and provide reliable, lifetime map updates in most cases. Finally, the simplest method is a smartphone mount. While it doesn't put the map on your car's screen, it positions your phone's display in your line of sight, which can be just as effective for navigation.

Just plug your phone in. Seriously, if your car has Apple CarPlay or Android Auto, that's all there is to it. Use the USB port, plug in the cable, and your phone's maps—whether it's Google Maps or Apple Maps—will pop up on the car's screen. It's way better than the built-in nav because it's always updated with the latest traffic and road changes. No fuss, no expensive updates.

I always use the built-in navigation in my SUV. I find it more reliable than depending on my phone's signal, especially on long trips through areas with spotty coverage. The maps are stored locally in the car. The turn directions also appear in my digital instrument cluster, which I prefer. The only downside is that I had to pay for a map update a couple of years ago, which was a bit of a hassle.

For my older sedan, I bought a Garmin GPS unit. It was a one-time cost and came with lifetime map updates. I just stick it to the windshield, and it works every time without needing my phone. The screen is big and easy to see. It’s a perfect solution if your car doesn't have a fancy screen or you don't want to use your phone's data plan for navigation all the time.

The best approach depends on your car's age and your budget. For most people with a car made in the last five years, smartphone projection is the winner. It's cost-effective and always current. If you have an older car without a compatible screen, a dedicated GPS device is a solid, dedicated solution. Built-in systems are convenient but often come with hidden long-term costs for updates. Weigh the pros and cons of integration versus ongoing expenses.
