Frequently Asked Questions

Everything you need to know about HGV Nav — from setting up your vehicle profile to understanding lane guidance and intelligence layers.

Getting started Routing Navigation & overlay Maps Intelligence & alerts Data & privacy Troubleshooting

Getting started

Does HGV Nav support Apple CarPlay? +

Yes. Connect your iPhone via USB or wireless CarPlay and HGV Nav automatically launches on your vehicle display. CarPlay provides turn-by-turn truck guidance, distance countdowns, lane indicators, and speed limit warnings designed for cab infotainment screens.

How much does HGV Nav cost? Is there a free trial? +

HGV Nav is £3.99 per month for complete access to all commercial vehicle navigation features, live intelligence layers, offline maps, and Apple CarPlay. Every new subscription includes a 3-day free trial with zero upfront charge, and can be managed or cancelled anytime directly in your iPhone Apple Account settings.

How do I enter my vehicle height and weight? +

Tap the parameter strip at the bottom of the map screen — it shows your vehicle type, height, and weight as chips. Tapping anywhere on the strip opens your full vehicle profile where you can edit height, width, length, gross weight, axle load, number of axles, trailer type, fuel type, and hazmat class.

Dimensions are stored locally on your device and used for every route calculation until you change them.

What transport types does HGV Nav support? +

HGV Nav supports 14 transport types. Only HGV types activate full truck restriction routing — other types use standard routing without dimension filtering.

  • HGV Artic — articulated lorry with drawbar or fifth-wheel coupling
  • HGV Rigid — rigid lorry with or without drawbar trailer
  • HGV Drawbar — rigid with drawbar trailer (longer overall length)
  • Coach / Bus — large passenger vehicle with height restrictions
  • Minibus — lighter vehicle restrictions
  • Campervan / Motorhome — height restriction routing enabled
  • STGO Cat 1 — abnormal load routing, 60 mph max
  • STGO Cat 2 — abnormal load routing, 40 mph max
  • STGO Cat 3 — abnormal load routing, 30 mph max, police notification required
  • Car, Motorcycle, Bicycle, Pedestrian — standard routing
How do I plan a multi-stop route? +

In the route planner panel, tap the + button to add a waypoint. You can add multiple intermediate stops between your start and destination. Drag the rows to reorder them. Each leg is routed using your full truck profile.

What is what3words and how do I use it? +

what3words divides the world into 3m × 3m squares, each with a unique three-word address (e.g. ///filled.count.soap). It's particularly useful for directing to loading bays and yard entrances that don't have a clear postal address.

Type /// followed by the three words in the search box. HGV Nav resolves the address and routes to that exact point.

Routing

How does truck-safe routing work? +

Your vehicle dimensions (height, weight, width, length, axle count) and hazmat class are checked against comprehensive commercial road databases. The system filters out:

  • Bridges and tunnels with clearance below your vehicle height
  • Roads with weight limits below your gross vehicle weight
  • Hazmat exclusion zones matching your declared hazmat class
  • Roads physically unsuitable for your vehicle category

HGV Nav automatically calculates truck-safe routes enforcing all clearance, axle, and weight criteria before departure.

What is the difference between Fastest, Practical, and Shortest? +
  • Fastest — minimises travel time, uses motorways and dual carriageways freely. Best for time-critical deliveries.
  • Practical — balances time and road type. Good default for most HGV runs.
  • Shortest — minimises total distance, may use slower roads. Useful when fuel cost matters more than time.
Why did the app route me down a road my truck can't use? +

Commercial bridge height and weight restriction databases are updated continuously, but physical road signs always take legal precedence.

Always obey physical road signs, which take legal precedence over navigation guidance. If you encounter a restriction not shown in the app, do not proceed past it.

To report a consistent error, email support@hgvnav.com with the road name and restriction details so we can flag it with our data providers.

How do I avoid tolls or motorways? +

Tap the Tolls or Motorways chips in the route options bar just above the map. Active avoidances are highlighted in green. The route recalculates immediately.

What commercial routing capabilities does HGV Nav provide? +

Commercial Restriction Routing — avoids low bridges, tunnels, weight-restricted roads, axle weight limits, and hazardous material exclusion zones.

Real-Time Traffic & Jam Detection — continuous monitoring of live road congestion, incidents, roadworks, and bottleneck avoidance along your route corridor.

High-Clarity Maps & Offline Downloads — clean vector rendering, high-resolution satellite imagery, and downloadable offline territories for zero-signal areas.

Does HGV Nav support STGO abnormal load routing? +

Yes. HGV Nav includes STGO Cat 1 (60 mph max), Cat 2 (40 mph max), and Cat 3 (30 mph max) as transport types, each with preset abnormal load dimensions and the correct legal speed cap applied to the speed limit display. However, HGV Nav does not provide statutory route authorisation — STGO movements require formal notification to National Highways and the relevant police forces. Always comply with your movement order.

Maps

Which map style should I choose? +
  • Commercial 3D Driving — high-contrast truck navigation map with 3D buildings, dynamic perspective, and clear road markings.
  • High-Contrast Day — bright daylight readability designed for direct cab sunlight.
  • Cab Night Vision — deep dark mode to minimize cabin glare and fatigue during overnight trunking.
  • Satellite & Detailed — high-resolution aerial imagery to inspect delivery yards, depot gates, and tight turning areas.

Switch in Settings → Map & Display → Map Style.

How do I switch between heading-up and north-up? +

Go to Settings → Map & Display → Map orientation and choose:

  • Heading Up — rotates the map so your direction of travel is always at the top. Most drivers find this more intuitive while moving.
  • North Up — keeps north fixed at the top like a traditional paper map. Useful for planning and longer-distance overview.
How does live traffic detection work? +

HGV Nav continuously monitors live road congestion, incidents, roadworks, and closures along your active route.

Delay times are calculated dynamically against free-flow speeds so your ETA is always realistic and you can avoid bottlenecks before you reach them.

Which languages are supported? +

HGV Nav supports 8 languages: English, Polish, Romanian, Urdu, Punjabi, French, Spanish, and German. Switch instantly from the language selector on the main screen.

Can I save routes and favourite destinations? +

Yes. Recent and favourite shortcuts appear on the main page, with the latest 3 visible for quick access. A dedicated route history page shows the full list when you need more.

Can I use satellite view? +

Yes. During navigation, tap the Sat / Map button to toggle high-resolution satellite aerial imagery. You can also enable Auto Satellite Near Destination in Settings to automatically switch to satellite view when approaching delivery yards and turning circles.

Intelligence & alerts

What is Yard Intel? +

Yard Intel is a community database of driver-submitted notes for delivery yards, warehouses, and depots. Notes can include access codes, restricted-height approach roads, preferred bay numbers, site difficulty ratings, and photos.

Yard Intel markers appear on the map as coloured pins. Tap one to read the notes left by other drivers. Submit your own via the Yard Intel tab — no account needed. Reports are anonymous and contain only the GPS coordinate, your text, and any photo you choose to add.

What alerts and overlays can HGV Nav show? +

Intelligence layers are toggleable in Settings → Route Intelligence. Depending on your settings, HGV Nav can show:

  • Low bridge and restricted height warnings
  • Level crossing locations
  • National Highways and roadside weigh stations
  • Speed camera positions
  • Fuel stations with live diesel prices
  • HGV truck stops and parking areas
  • Live traffic incidents and road closures
  • National Highways variable message signs
  • TfL disruptions and ULEZ zone boundaries
  • Roadworks with expected delays
  • STGO-approved abnormal load routes
  • Yard Intel community pins
Why aren't some intelligence layers showing? +

Check that the layer is enabled in Settings → Route Intelligence. Certain layers (such as live congestion, variable motorway signs, or TfL Direct Vision Standard) activate only when relevant to your active route, vehicle profile, or geographic area. Layers requiring live data also require an active internet connection.

What is the Route Traffic bar? +

The vertical bar on the right side of the map shows the density of alerts along your planned route. Coloured markers on the bar represent incidents, low bridges, speed cameras, and other alerts at proportional positions along the route from top (start) to bottom (destination).

Tap a marker to jump the map to that alert.

Data & privacy

Does HGV Nav track my location or store my data? +

HGV Nav does not store your location on its own servers. Your GPS is processed locally on-device for navigation — HGV Nav holds no location history.

All app preferences and vehicle settings are stored locally on your device using Apple's standard storage. Read the full Privacy Policy for details.

Can I use HGV Nav offline? +

Route calculation and speed limit alerts require an internet connection. However, you can download map regions for offline rendering via Settings → Offline Maps. The map renders without mobile data once downloaded; only recalculation and live traffic layers require connectivity.

How do I delete my data? +

All preferences and checklist data are stored locally on your device and deleted when you delete the app. If you submitted Yard Intel reports and want them removed, email support@hgvnav.com with the location and approximate date of the report.

Troubleshooting

The route isn't calculating +

Check your internet connection. If route calculation fails, it is usually a temporary connection loss or an unsupported vehicle/region combination — wait a moment and try again.

If the problem persists, email support@hgvnav.com with the origin and destination you were trying to route.

Speed limits are showing wrong +

Speed limit data comes from commercial road databases and is regularly updated but may lag behind recent sign changes. On National Speed Limit roads (no posted number), HGV Nav shows 60 mph for single carriageway and 70 mph for dual carriageway and motorway.

Always follow the physical sign. If a specific road consistently shows the wrong limit, email us the road name and location so our team can update the network data.

Lane guidance strip isn't appearing +

The lane guidance strip appears when: (1) lane guidance is enabled in Settings, (2) road network data includes lane counts for the upcoming manoeuvre, and (3) there is more than 1 lane. Many rural roads do not have lane counts, so the strip will not show on those sections.

The app crashed or isn't loading +
  • Force-close and reopen the app.
  • Check you're running iOS 18 or later.
  • Make sure you have a working internet connection.
  • Delete and reinstall the app (note: locally stored preferences will be reset).

If the problem persists, email support@hgvnav.com with your device model, iOS version, and a description of what happened.
