Yes, a spouse can generally install a navigator (like a GPS device) in a car they co-own or regularly use, as long as it's done safely and doesn't damage the vehicle. The key considerations are legality, installation method, and your spouse's preferences. The simplest and most common method is a suction cup or adhesive mount on the windshield or dashboard. However, some states have specific laws about windshield obstructions, so placement is important for both safety and compliance.
The primary concern isn't permission, but rather the method of installation. A poorly installed device can become a dangerous projectile in a sudden stop or crash. Permanent modifications, like hardwiring the GPS into the car's electrical system, should ideally be discussed beforehand, especially if it's a leased vehicle or if your spouse is particular about the car's interior. For most modern vehicles, using the 12-volt power outlet (cigarette lighter) and a non-destructive mount is a perfectly acceptable and reversible solution.
If you're comparing a dedicated GPS unit to using a smartphone, the dedicated device often has advantages in reliability, screen visibility in direct sunlight, and not draining your phone's battery. Here’s a quick comparison of popular GPS mounting options:
| Mounting Method | Best For | Pros | Cons |
|---|
| Suction Cup (Windshield) | Temporary use, rental cars | Very strong hold, easy to adjust and remove | Can obstruct view, may be illegal in some states if on windshield |
| Adhesive Dashboard Disk | Permanent spot on dashboard | Stable, no view obstruction, legal everywhere | Leaves adhesive residue, semi-permanent |
| CD Slot Mount | Cars with unused CD players | Extremely stable, no adhesive or suction marks | Only works with a CD slot, can block climate controls |
| Vent Clip | Lightweight devices, quick setup | Easy on/easy off, no residue | Can block air vents, less stable on rough roads |
| Friction Dash Mount | Flexible positioning on dashboard | No adhesive, highly adjustable, works on textured surfaces | Can slide on some materials during hard acceleration |
Ultimately, clear communication with your spouse is the most important step. A quick conversation ensures the chosen location works for both the driver's visibility and the vehicle's aesthetics.
