The best phone mount for Google Maps sat nav in the UK is a stable dash or low-windscreen mount with a clamp-style cradle, placed so it doesn’t block your view of the road. Examples include the RAM Mounts X-Grip on a suction or dash base, and vehicle-specific Brodit holders if one exists for your car.
The law matters as much as the mount: in the UK the phone must be in a holder and you must not hold it while driving. Below are the mount types compared, where to place one legally, and what to check before buying.
Best Phone Mount for Google Maps Sat Nav: Mount Types Compared
| Mount type | Stability | View of map | Watch out for |
|---|---|---|---|
| Windscreen suction | Good on smooth glass | Best (near eye line) | Must stay out of your view of the road; suction can drop in heat or cold |
| Dashboard (suction or adhesive) | Good to very good | Good | Textured dashes may need an adhesive disc; adhesive can mark some surfaces |
| Vehicle-specific (e.g. Brodit) | Very good | Good, factory-like position | Only available for certain models; check your exact car and year |
| Air vent clip | Fair | Lower, quicker glance down | Weak or round vents; heavy phones can sag |
| CD slot | Fair to good | Low | May block screen or buttons |
| Magnetic / MagSafe | Varies with magnet strength | Depends on base | Thick cases weaken the hold; non-MagSafe phones need a metal plate |
Recommended Options
RAM Mounts X-Grip
A spring-loaded clamp cradle that fits a wide range of phones, mounted on a RAM suction cup, dash or drill base. It is popular because the ball-and-socket arm is stiff and parts are replaceable. The trade-off is size: it is bulkier than a slim vent clip.
Vehicle-specific holders
Brands such as Brodit make clips shaped for particular car dashboards, so there is no suction cup or adhesive. They are a good fit for UK drivers who want a tidy, permanent position. See our model-specific guides for the Mercedes E-Class W213 and Hyundai Tucson.
MagSafe mounts
Quick to use with iPhone 12 or newer and a MagSafe-compatible case. Hold strength varies a lot between brands. Our MagSafe car holder guide covers what to check.
Where to Mount a Phone for Sat Nav in the UK
- Not in your line of sight to the road. It is an offence to drive without a full view of the road ahead.
- Avoid the area right in front of you within the wiper sweep. Department for Transport guidance treats a 290mm-wide strip centred on the steering wheel as the most critical zone.
- Low on the windscreen or on the dash is usually the best balance of visibility and legality.
- Not over airbag covers or where it blocks controls.
- Within easy glance, so you look away from the road for as little time as possible.
The UK Law on Phones as Sat Nav
- You may use a phone for navigation if it is secured in a holder and you don’t hold it while driving.
- Holding and using a phone while driving can mean 6 penalty points and a £200 fine; new drivers can lose their licence.
- You must still be in proper control. Police can stop you if they think you are distracted, even if the phone is in a holder.
- Set your Google Maps route before setting off. Use voice commands or pull over safely to change it.
This is a summary, not legal advice. Check the current Highway Code and GOV.UK guidance.
Will It Hold on Rough UK Roads?
- Clamp cradles hold better than minimal-contact magnetic pads over potholes and speed cushions.
- Short arms vibrate less than long goosenecks.
- Rubber-lined contact points reduce rattle.
- Clean the glass or dash before fitting suction cups, and recheck them in very hot or cold weather.
Checklist Before You Buy
- Phone size and weight, with your case on.
- Side buttons and charging port stay clear.
- Your dashboard surface (smooth, textured or curved) suits the base.
- Vent blade shape, if you are considering a vent mount.
- Charging: a cable route or Qi/MagSafe charging for long journeys.
- One-handed release, so you are not fiddling at junctions.

FAQ
Is it legal to use Google Maps on a phone while driving in the UK?
Yes, if the phone is secured in a holder, you set the route before you set off, and you don’t hold the phone while driving. Holding a phone for any reason while driving can lead to 6 penalty points and a £200 fine.
Where should I mount my phone on the windscreen in the UK?
Keep it out of your view of the road. Department for Transport guidance on windscreen obstructions treats the 290mm strip in front of the driver within the wiper sweep as the critical zone. Low on the windscreen near the dashboard, or on the dash itself, is usually best.
Can I touch my phone in a holder to change the route?
Rules on touching a phone in a cradle are less clear. Police can still stop you if they think you are not in proper control. The safest approach is to set the route before driving and use voice commands or pull over safely to make changes.
Are air vent phone holders good for sat nav?
They work in many cars, but the phone sits lower than on the windscreen and some vents are too weak or have round or vertical blades. Check your vent design and phone weight before buying.
What is the most stable phone mount for UK roads?
Mounts with a solid base and a clamp-style cradle, such as a RAM X-Grip on a suction or drill base or a vehicle-specific Brodit holder, generally move less on potholes and speed bumps than small magnetic or vent mounts.
Will a phone mount fail my MOT?
An item that doesn’t impair the driver’s view of the road should not cause a fail, but a mount in the main viewing area in front of the driver can. Removing the mount before the test avoids any doubt.
