Equipped with SmartNav™, the 337 ensures communication and navigation technology is always within reach. With its seven-inch, full-color touch screen, fully integrated audio system, GPS navigation and voice-activated phone and messaging, SmartNav works as your advanced driver control center.

To enable smooth navigation through city traffic, SmartNav’s onboard GPS navigation system uses CoPilot Live to find routes customized to your vehicle’s size and weight. Additionally, SmartNav’s real-time speed limit warnings, custom mapping and time of arrival and fuel cost estimates make driving the 337 safer, more efficient and more economical.

Built-in Bluetooth technology ensures you’re always connected, whether you’re already on the job or heading to your destination. SmartNav pairs with your smartphone via Bluetooth, enabling hands-free, voice-activated access to contacts, phone calls and messaging so you can stay safe while you stay in touch.

Equipped with the PACCAR PX-9 engine – which features one of the highest power-to-weight ratios in its class – and featuring the Common Rail Fuel System for high-performance fuel economy and cleaner, quieter operation, the 337 makes hard work look easy. With the PACCAR PX-7, simple tasks can be achieved with weight savings and efficiency.



The 337 is available with your choice of Bendix® Wingman® Advanced™ or Wabco OnGuardACTIVE™, two collision mitigation technologies designed to make operating your truck safer. With real-time alerts that let you know when your truck’s following distance closes, and active braking technology ready to help you avoid dangerous obstacles, each system keeps you in control on busy city streets.

To enhance fuel economy and enable longer cruising at safe speeds, both Bendix Wingman Advanced or Wabco OnGuardACTIVE systems come with adaptive cruise control, which uses on-board sensors to automatically adjust your speed based on forward vehicle distance.

Through selective braking, both Bendix ESP and Wabco SmartTrac™ ESC use automatic intervention technology to provide more stability, better directional control and a safer drop in speed during high-risk situations.
