Yes, you can generally use a non-assisted, standalone GPS device in a newer car. The primary method is through a suction cup mount on your windshield or dashboard, plugging the device into a 12V power outlet (formerly known as a cigarette lighter). While it will work for basic navigation, its integration with the car's systems is limited compared to built-in or smartphone-based solutions.
The main challenge is not compatibility but convenience. Newer cars often come with large, high-resolution infotainment screens running Apple CarPlay or Android Auto. These systems project navigation apps like Google Maps or Waze directly onto the display, offering real-time traffic, voice control, and a more seamless experience. A standalone GPS can feel redundant and clutter your dashboard.
Pros and Cons of Using a Standalone GPS in a Modern Car
| Feature | Standalone GPS Device | Smartphone (CarPlay/Android Auto) |
|---|
| Signal Reliability | Does not require a cell signal; uses satellite. | Requires a consistent cellular data connection. |
| Data Costs | No ongoing data fees after purchase. | Uses your mobile data plan. |
| Real-Time Updates | Traffic updates often require a separate subscription. | Live traffic, road closures, and rerouting are standard. |
| User Interface | Can be slower and less intuitive than modern apps. | Familiar, frequently updated interface from your phone. |
| Integration | Limited to none; audio directions may interrupt music. | Deeply integrated; audio mixes with music, Siri/Google Assistant voice control. |
| Mounting | Requires a separate mount and power cable. | Often connects wirelessly, with the phone staying in your pocket. |
If your car lacks smartphone integration or you frequently travel through areas with poor cell service, a dedicated GPS is a valuable tool. For most drivers in urban and suburban areas, however, using their phone via the car's infotainment system provides a superior, more integrated navigation experience.
