How to Get a GPS Toll OBU Device — Registration & Installation Guide

Everything about the On-Board Unit (OBU) for India's new GNSS toll system — where to get it, how to install, how to link your account, and what to expect.

The On-Board Unit (OBU) is the small GPS device you'll need for India's new satellite-based toll system. It replaces the FASTag sticker and tracks your highway distance via GNSS satellites. Here's everything about getting, installing, and using it.

Quick Facts

●Device: On-Board Unit (OBU)
●Cost: ₹1,000–₹1,500 (expected)
●Powered by: GNSS (GPS + GLONASS + NavIC)
●Installation: Dashboard/windshield mount
●Linking: Bank, wallet, or UPI AutoPay
●For new vehicles: Pre-installed by manufacturer
●For old vehicles: Retrofit kit available

What Is an OBU (On-Board Unit)?

An OBU is a compact electronic device installed inside your vehicle that communicates with GNSS satellites (GPS, GLONASS, and India's NavIC). It tracks your vehicle's entry and exit points on tolled highway sections, calculates the distance driven, and transmits this data to the NHAI toll processing centre for automatic charge deduction.

Expected Cost

Based on pilot programs and government statements, the OBU is expected to cost ₹1,000–₹1,500 as a one-time purchase. This includes the device and initial setup. Similar to how FASTag was introduced with a minimal cost, the government is likely to subsidise OBU pricing to ensure mass adoption. Some banks and NHAI partners may offer free or discounted OBUs as introductory offers.

Where to Get an OBU

Once the system rolls out, OBUs will be available at:

›NHAI toll plazas and points of sale (similar to current FASTag counters).
›Authorised banks and payment companies (SBI, ICICI, Paytm, etc.).
›Petrol pumps and authorised automobile service centres.
›Online portals — likely via the NHAI or iHMCL website.
›For new vehicles: manufacturers may pre-install OBUs (like FASTag is pre-fitted today).

Installation Process

The OBU installation is expected to be simple and quick:

›Step 1: Visit an authorised OBU installation centre with your vehicle.
›Step 2: Submit vehicle documents — RC copy, insurance, owner ID proof.
›Step 3: Pay the one-time device fee (₹1,000–₹1,500).
›Step 4: Technician installs/mounts the OBU inside the vehicle (dashboard or windshield area).
›Step 5: OBU is activated and linked to your mobile number and payment account.
›Step 6: Test drive verification — the centre may verify satellite connectivity.

Linking Your Payment Account

The OBU must be linked to a payment method for automatic toll deduction:

›Bank account (direct debit, similar to FASTag auto-top-up).
›Prepaid wallet (NHAI wallet, Paytm, PhonePe, etc.).
›UPI AutoPay (likely to be supported for seamless deduction).
›Minimum balance requirements will be specified — similar to FASTag's ₹100 minimum.

For Old Vehicles (Retrofit)

If your vehicle doesn't have a pre-installed OBU, you'll need a retrofit kit. The device is compact and can be externally mounted. NHAI is working with device manufacturers to ensure compatibility with all vehicle types — two-wheelers (when applicable), cars, SUVs, buses, trucks, and commercial vehicles. The retrofit process is non-intrusive and does not require any modification to the vehicle's wiring or electronics.

What If OBU Is Not Available Yet?

Until OBU distribution begins in your area, continue using FASTag as usual. For vehicles without any electronic tag, ANPR cameras will capture your number plate and generate invoices. However, having an OBU will give you benefits like the 20 km free rule and barrier-free passage.
