Where Should You Mount Your Phone in a Car? 4 Options Compared

Modern cars already have larger infotainment screens, Bluetooth and built-in navigation, but plenty of drivers still prefer to keep their phone visible for maps, calls, music or other supported functions.

The harder question is often not whether you need a phone holder, but where the phone should actually go.

Windscreen mounts, vent mounts and dashboard mounts are all common, while screen-mounted holders are becoming another option in vehicles with larger centre displays. Each approach has advantages and compromises, and the best choice depends on your vehicle interior, phone and preferred driving position.

Here are the four main mounting positions worth comparing.

1. Windscreen Mount

Windscreen suction mounts remain one of the most familiar options.

They attach directly to the glass and usually offer plenty of adjustment through an arm or ball joint.

Advantages

• Wide range of positioning options

• Usually easy to install and remove

• Can place the phone relatively close to the driver's natural line of sight

• Works across many different vehicles

Things to consider

The main concern is visibility. A large phone, long mounting arm or poorly chosen position can obstruct part of the road view.

Suction cups can also become less secure over time, particularly if the glass or suction surface becomes dirty.

If you choose this style, keep the mount as compact as possible and check the position from your normal driving seat before using it on the road.

2. Air Vent Mount

Vent mounts attach directly to one of the vehicle's air vents.

They're popular because they're compact and generally don't require adhesive or a suction cup.

Advantages

• Compact design

• No adhesive on the dashboard

• Keeps the windscreen clear

• Usually easy to move between vehicles

Things to consider

Not every vent is suitable for supporting a phone.

Thin or unusually shaped vent slats may not provide enough support, while heavier phones can cause some mounts to tilt downwards.

A vent-mounted phone can also partially block airflow. This may be inconvenient when you're using heating or air conditioning, and the position of the vents varies significantly between vehicles.

For cars with distinctive or highly integrated vent designs, this is worth checking carefully before buying.

3. Dashboard Adhesive Mount

Dashboard mounts typically use an adhesive pad or base attached to the dashboard or trim.

They can provide a clean installation when there is a suitable flat surface available.

Advantages

• Flexible mounting location

• Doesn't necessarily obstruct the windscreen

• Can provide a low-profile installation

Things to consider

The biggest drawback is the adhesive.

Australian vehicle interiors can become extremely hot, and dashboard materials vary widely in texture and finish. Adhesive performance can therefore depend heavily on the mounting surface.

There is also the practical question of removal. If you change the mount later, you may be left with adhesive residue or marks on the trim.

For drivers who regularly change vehicles, accessories or mounting positions, this can make adhesive-based mounts less appealing.

4. Screen-Mounted Phone Holder

A less conventional option is mounting the phone holder directly to the vehicle's centre display.

This approach has become more relevant as EVs and newer vehicles increasingly use large, freestanding infotainment screens.

Rather than attaching to the windscreen, vent or dashboard, the bracket clamps onto a compatible section of the display housing.

Advantages

• No dashboard adhesive

• Leaves the air vents unobstructed

• Keeps the phone close to the vehicle's main display

• Can create a clean, integrated-looking setup

• Suitable for vehicles where conventional mounting locations are limited

Things to consider

Compatibility matters more with this type of mount.

The display needs a suitable flat-backed section with enough clearance for the bracket. You should also make sure the holder does not interfere with the screen, dashboard controls or any movement of the display.

This style is therefore better suited to certain screen designs rather than being completely universal.

For drivers interested in this type of setup, EV Heaven's CNC Aluminium Magnetic Screen Phone Holder uses a clamp-on design for compatible flat-backed displays between 6–18 mm thick, avoiding dashboard adhesive while allowing the phone position to be adjusted.

Magnetic or Clamp-Style Phone Holder?

The mounting position is only half of the decision. You also need to consider how the phone itself attaches to the holder.

Magnetic mounts

Magnetic mounts are convenient because the phone can normally be attached and removed with one hand.

They work particularly well when you frequently get in and out of the vehicle and want minimal hardware around the edges of the phone.

Check compatibility with your phone, case and magnetic system before buying.

Mechanical clamp mounts

Clamp-style holders physically grip the sides of the phone.

They can work with a wide range of devices and don't necessarily require a magnetic case or plate.

The trade-off is that they tend to be bulkier and can take slightly longer to load and remove.

Neither system is automatically better. The right choice depends on how you use your phone and the type of case you normally keep on it.

What About Large Phones?

Phone size has increased significantly in recent years, so stability matters.

If you use a large phone or a heavier case, look beyond whether the mount simply says it is "universal".

Consider:

• How firmly the vehicle attachment is secured

• How far the phone sits away from the mounting point

• Whether the joint can hold its angle under the phone's weight

• Whether the phone remains stable on rough roads

• Whether your case affects magnetic strength or clamp clearance

A compact mounting arm will generally place less leverage on the attachment point than an unnecessarily long one.

What Works Best in a BYD or Other Modern EV?

Large centre screens and unusual dashboard layouts can change which mounting method makes sense.

For example, a vehicle with narrow vents may not suit a traditional vent holder, while a large freestanding centre display may make a screen-mounted holder more practical.

Before choosing any mount, sit in your normal driving position and check:

1. Can you see the phone without blocking your view of the road?

2. Does it cover any part of the vehicle display or controls?

3. Does it interfere with an air vent?

4. Can you reach the phone without stretching?

5. Is the mount secure when the vehicle moves over uneven roads?

6. Can it be installed without permanently modifying the interior?

The answer may be different from one vehicle to another.

Don't Forget the Road Rules

A phone holder does not make every type of phone use legal while driving.

Rules differ between Australian states and territories and can also vary depending on your licence type. Learner and provisional drivers may be subject to significantly stricter restrictions than fully licensed drivers.

A mounted phone should be secured in a commercially designed holder and positioned so that it does not obstruct the driver's view.

Always check the current rules for your state or territory, and set up navigation, music and other functions before driving whenever possible.

So, Which Mounting Position Is Best?

There isn't one mounting position that works best for every car.

A windscreen mount offers flexibility but needs careful positioning.

A vent mount is compact and adhesive-free but depends heavily on the vehicle's vent design.

A dashboard mount can look clean but introduces adhesive and surface-compatibility considerations.

A screen-mounted holder can be a particularly neat option in vehicles with compatible freestanding displays, especially if you want to keep the windscreen, dashboard and air vents clear.

The best solution is the one that fits your vehicle securely, keeps important controls accessible and places the phone somewhere that does not interfere with your view of the road.
