About Gantry SG
Gantry keeps the things you actually need while driving — your ERP road-pricing charges, cashcard balance, speed, and road alerts — on a clear, always-on display in your car. Your phone does the work in your pocket; the display is what you watch. Gantry connects to your vehicle's OBU (On-Board Unit) using LTA's official OBU API/SDK, parses the ERP 2.0 messages, and relays just what matters to a dedicated in-car screen over Bluetooth. No more glancing at your phone to check a charge or a low balance. WHAT GANTRY SHOWS • ERP charges and cashcard deductions, the moment they happen • Your card balance — with a heads-up before it runs low • Current speed and speed-limit signs • Speed cameras, parking availability, travel times, and official LTA road-sign alerts • A big, legible clock and speed when nothing else needs your attention BUILT TO STAY OUT OF YOUR WAY • A priority-driven layout decides what matters most at each moment • A built-in preview mirrors the display, so you can set it up and confirm it works before you drive • An Activity feed logs every charge, deduction, and alert so nothing goes unnoticed • Live Activities and widgets keep your balance on the Lock Screen and trip status in the Dynamic Island • Pair by scanning a QR code — then it reconnects automatically every time you get in • Customise brightness, theme, which alerts to show, message timing, speed, and clock OVER-THE-AIR UPDATES New display firmware is delivered straight from your phone over Bluetooth — verified before installing, with automatic rollback for safety. No wires, no computer. REQUIRES THE GANTRY DISPLAY Gantry is the companion app for the Gantry Display, a round AMOLED screen for your car powered by a single USB-C cable. The app's job is to bridge your OBU and the display — it is not a standalone dashboard, and the hardware display is required to use it. Learn more and order at gantrydisplay.com. Built for Singapore's next-generation ERP.
