Choose a smartphone that lets you download the campsite route before entering a weak-signal area, then check that its screen fits a safe, readable mount and that you have a charging plan. Both Google Maps on Android and Apple Maps on a compatible iPhone offer offline navigation, but their coverage and features differ; your existing apps, available storage and in-car setup may settle the choice.
If the campsite approach may lose mobile coverage, download the relevant area before leaving and allow room for maps on the phone. Google Maps Help says its offline driving directions require the entire route to fall within the downloaded map; Apple Support confirms that offline maps use device storage.
Check whether the phone and holder provide a readable view without obstructing the road. GOV.UK says a driver must not hold and use a phone while driving; hands-free use still requires a clear view and full control of the vehicle.
If you already use Android or iPhone services, you can assess offline maps without changing platforms solely for this trip. Google Maps Help documents offline driving directions on Android, while Apple Support documents offline Maps on iPhone with iOS 17 or later, subject to area availability.
Start with the mapping app and the full route it must cover. Then assess how the phone will be mounted and powered before comparing handset specifications.
| Concern | What to check | Who this matters to |
|---|---|---|
| Directions without signal | Check offline driving support, free storage and whether the downloaded area covers the whole route. Google Maps Help says offline mode does not provide live traffic or alternative routes. | If signal drops on the campsite approach, I need directions that remain available for the entire drive. Around 36% of consumers put route continuity first. |
| Safe in-car use | Check mount fit and placement, and set the destination before moving. Under GOV.UK guidance, a driver must not hold and use the phone, block their view of the road or lose control of the vehicle. | When I am driving, I need to see the next turn without picking up the phone or obscuring the road. Safe mounted use is the main concern for roughly 29% of consumers. |
| Power and outdoor use | Compare the exact model’s battery, display and water-resistance specifications, then plan compatible in-car charging. Manufacturer battery figures do not establish navigation runtime. | For a long day of directions and campsite stops, I want a workable charging plan and a screen I can read outdoors. About 21% of consumers prioritise this combination. |
| Apps and accessories | Confirm that your preferred map app supports the required offline area, and check the phone’s storage and the charging equipment you already own. | If I am replacing a familiar phone, I want my maps and travel setup to remain straightforward to use. Existing services and accessories come first for around 14% of consumers. |
Google Maps Help says offline driving guidance needs the entire route inside the downloaded area; live traffic and alternative routes are unavailable offline. Apple Support says its offline maps use storage and are available only in selected areas.
Download the campsite and approach roads before departure. While safely parked, test the route with mobile data turned off.
GOV.UK says drivers must not hold and use a phone while driving. A hands-free device must not block the view of the road and traffic ahead, and the driver must remain in full control.
Fit the holder where it leaves the road view clear, set directions before moving and use voice prompts rather than handling the phone.
A compatible holder and an in-car charging connection may also be needed.
Battery capacity and manufacturer endurance claims are useful model specifications, but they do not establish how long a particular phone will run your navigation app with its chosen brightness and connection.
Compare figures on the same stated basis, arrange charging for the journey and try your chosen app on a trip before relying on battery power alone.
Water-resistance ratings describe tested conditions for a specific model, not a promise against all water exposure. Apple, for example, specifies the iPhone 16’s IP68 rating with a depth and time limit under IEC 60529.
Check the exact model’s rating and care guidance, and keep its charging port dry before connecting power.
A reference point for Android users planning to navigate with Google Maps. The Google Store UK specifications for Pixel 9a list a 160 mm display, a typical 5,100 mAh battery and an IP68 rating.
Samsung UK lists the Galaxy S25 as a 6.2-inch Android option with location systems including GPS and Galileo. Its size offers a different mount-fit consideration from a larger phone.
An option for people who already use iPhone and Apple Maps. Apple Support documents offline maps on iPhone with iOS 17 or later; Apple’s iPhone 16 specifications list a 6.1-inch display and an IP68 rating.
These Android and iPhone models offer different screen sizes and storage configurations to consider for downloaded maps and mounted viewing. For any model, confirm your preferred app’s offline coverage, holder fit and charging setup before the trip.

If downloaded maps are central to your trip, check the space left on this Android phone after your usual apps and photos.
The product name specifies GPS, 64GB storage, a 6.56-inch display, a 5,000 mAh battery and IP54. It also lists card expansion; check where your mapping app stores offline maps rather than assuming it can use a card.
No. GOV.UK says it is illegal to hold and use a phone or other device that can send or receive data while driving, including when stopped at traffic lights or in a queue. Set the route before moving, or stop somewhere safe before handling the phone.
Yes, hands-free navigation can be permitted under the conditions stated by GOV.UK: do not hold the phone, do not block your view of the road and traffic ahead, and remain in full control of the vehicle. A mount does not remove the need to avoid distraction.
They can, provided the app and downloaded area cover the journey. Google Maps Help says its offline driving route must lie entirely within the downloaded map and will not include live traffic or alternative routes. Apple Support says offline Maps navigation is available on iPhone with iOS 17 or later in selected areas.
Download the campsite and approach roads, check that the complete route is covered, and set your destination before driving. Allow storage for the map, charge the phone and check that its holder and in-car charging connection are suitable.
No IP rating promises protection in every situation. For the iPhone 16 specifically, Apple states an IP68 rating under IEC 60529, tested to a maximum depth of 6 metres for up to 30 minutes. Check the conditions and care guidance for the exact phone you choose.
