The Chevrolet Silverado is America’s second best-selling vehicle and a genuine workhorse. For drivers who haul, tow, and put serious miles on their truck, a head-up display adds the kind of engine awareness that matters on a working vehicle.
OBD2 port location in Silverado
On all 1996+ Silverado 1500 and 2500 models, the OBD2 port is under the driver-side dashboard, to the left of the steering column. It accepts any standard OBD2 connector without an adapter.
Best pick for Silverado work trucks: OBD2 Pro
The OBD2 Pro is purpose-suited to the Silverado work truck. Towing and hauling stress the engine more than light-duty driving; monitoring coolant temperature and battery voltage while under load catches problems before they become expensive. GPS speed verification is also useful when hauling load changes the speedo accuracy.
Best for Silverado personal use and highway driving: GPS Lite
If you primarily want clean speed visibility without OBD2 complexity, the GPS Lite plugs into the 12 V socket and gives you accurate GPS speed on the wide Silverado windshield. The truck’s large, nearly-vertical windshield projects a particularly clear HUD image.
Towing-specific HUD benefits
- Speed discipline — speed limits are typically lower when towing; a visible speed readout helps compliance
- Coolant monitoring — trailer brakes, tongue weight and grade climbing can push coolant temperatures into warning territory faster than normal
- Voltage monitoring — trailer brake controllers draw current; an OBD2 HUD can flag a weak battery or alternator before you are stranded

Frequently asked questions
Does the Chevy Silverado have a factory head-up display?
A factory HUD was added to the Silverado High Country trim from 2022 onward. Earlier models and lower trims have no factory HUD, making an aftermarket unit a popular add-on for the majority of Silverados on the road.
Can I use an OBD2 HUD while towing with a Silverado?
Yes, and it is particularly useful. Towing increases engine load significantly — monitoring coolant temperature and voltage while towing warns you of stress before it causes damage. The OBD2 HUD is the recommended choice for Silverados used for regular towing.
Where is the OBD2 port in a Silverado?
Under the driver-side dashboard to the left of the steering column. On 2019–2025 Silverados it is easy to access; on older models it may be behind a small trim panel. It is a 16-pin trapezoid socket.
