From recent reviews.
About V2X2MAP
V2X2MAP makes invisible traffic radio visible: the app shows the C-ITS/ITS-G5 messages that traffic lights, vehicles and roadwork warning trailers around you broadcast on 5.9 GHz – live on the map, on the Lock Screen and in CarPlay.
IMPORTANT – RECEIVER REQUIRED: An iPhone cannot receive this radio by itself.
Check https://v2x2map.com/ how to get a receiver.
The app needs an ESP32-C5 microcontroller as receiver, flashed once with our free open-source firmware.
Without the receiver the map stays empty – to try it out, start the demo drive.
WHERE IT WORKS: the app receives the European standard ETSI ITS-G5 (5.9 GHz) as broadcast by traffic lights and vehicles mainly in Europe. Other V2X systems such as C-V2X (e.g. China) or ITS Connect (Japan) cannot be received. The demo drive works everywhere.
HOW TO SET UP THE RECEIVER (once, about 2 minutes)
1. Connect the ESP32-C5 to a computer with a USB cable.
2. Open v2x2map.com/flash in Chrome or Edge and click “Connect & Flash” – the firmware is written in about a minute.
3. Unplug the receiver once and plug it back in. From then on it runs from any USB charger, power bank or the USB port in your car.
4. Open V2X2MAP – the setup guides you through every step: the app finds the receiver “ITS-G5-RX” via Bluetooth and connects – no account, no pairing code. After that it connects automatically in the car.
FEATURES
• Traffic-light assistant: when approaching, the signals of your approach per direction (left / straight / right) with the colour as a word, remaining time and distance – already from about 300 m as a preview
• Green-wave speed: the speed at which you arrive on green – never above the speed limit
• CarPlay: a large, easy-to-read traffic-light board and an info overview right in the car
• Live Activity on the Lock Screen and in the Dynamic Island
• Warnings about emergency vehicles heading your way and hazard warnings (e.g. roadworks, end of a traffic jam) as notifications – also in the background
• Lane-level intersection maps with your lane and turn arrows on Apple Maps
• Country rules for Europe and the UK: red-and-amber, turn signals, left-hand traffic, km/h or mph
• List of all stations nearby with details
• Record drives and replay them later
• Optional: forward received messages to the open project OpenTrafficMap (off by default)
The displays are for information only and never replace watching the road and the actual traffic lights – traffic rules and the real signal always apply. Receiving radio services may be regulated in your country – see the note inside the app.

Latest updates
2.0
Our biggest update yet:
• New three-step setup: notes and permissions, a receiver guide to tick off, and a driving profile in one tap – available again any time under Settings → “Set up receiver”.
• See lights earlier: the next traffic light appears from about 300 m as soon as the approach is clear.
• The light disappears right after the stop line and the next one takes over immediately.
• More accurate matching at large junctions: pedestrian signals are no longer shown as car signals.
• Redesigned CarPlay: larger signals, the colour as a word (also for colour-blind drivers), distance under every signal, green-wave speed in its own row, a calm screen when no light is near, a smooth change to the next light.
• Turns that must yield to pedestrians show a flashing hint; flashing amber is shown as “Flashing amber”.
• Wide junctions with several turn and straight-ahead lanes.
• Country rules for Europe and the UK: red-and-amber only where it exists, left-hand traffic, mph and yards.
• New sound when your light turns green; emergency-vehicle warning only when it is heading your way.
• New languages: French, Czech, Spanish, Chinese, Japanese and Korean.
• Supports the new receiver firmware 2.0 with a faster Bluetooth link.
