Driver Mobile App

Remotely control cabin climate for when you’re away — no need to leave the unit on while you’re gone. Start climate control before coming back to the truck just by using your phone. The mobile app includes other useful features, like an automatic alarm clock to remind you it’s time to roll.

Self-Teaching Computer

Learns your preferences automatically and adapts how the APU runs — saving an estimated 400 gallons per year at the national average diesel price of $5.345/gal.

Instant Alarm Codes

Fleets and drivers can see alarm codes immediately without the need to visit a service center, speeding up diagnosis and reducing downtime.

Battery Protection

Continuously tracks battery voltage and automatically starts the APU to ensure your batteries never die.

Hours Tracking & Service Intervals

Use the Fleet Portal to track engine and bunk heater hours across your fleet, ensuring preventative maintenance is performed on time — every time.

Mobile Connectivity

Built-in cellular with its own data connection allows Neon to offer the optional Premium Connectivity package — unlocking unlimited cabin Wi-Fi for internet & video streaming during your break.

Better for Drivers. Better for Business.

Neon doesn't just help drivers — it gives fleets real visibility and cost savings across the board.

Improved Driver Retention

Drivers stay with fleets that invest in their comfort. Neon’s mobile app, smart climate system, and cabin Wi-Fi make a real difference — bringing value beyond fuel savings.

21% Lower Service Costs

Instant alarm codes and hours tracking ensure preventative maintenance happens sooner — reducing service costs by an estimated 21%.

400+ Gallons Saved Per Year

The Self-Teaching Computer intelligently adapts how the APU runs, saving over 400 gallons of fuel annually per truck at the national average diesel price of $5.345/gal.

Fewer Roadside Calls

Automatic battery voltage monitoring and APU start prevents the most common cause of roadside service calls. With a single jump-start averaging up to $300, Neon pays for itself while increasing on-time reliability.

Your HMI Still Works

Neon sits between the existing HMI controller and the ECU. In the unlikely event that your Neon suffers a malfunction, your existing HMI can take over immediately. Reliability and driver preference are always honored.
