Factory dash gauges only tell you so much. If you tow, haul, or run a modified truck, you want to see what's really going on with temps, pressures, and engine data before a small problem turns into an expensive one. The Edge Insight CTS4 puts that information on one bright screen without bolting a row of gauge pods to your pillar.

The CTS4 is Edge's newest Insight monitor and fits most 1996 and newer OBDII vehicles. It plugs into the OBDII port, mounts in the cab, and reads supported vehicle data in real time. It is a monitor only, with no tuning, and it can be upgraded later to an Evolution CTS4 or Insight+ CTS4 through an internet update.

What you get:

• New Edge Insight CTS4 digital gauge monitor with OBDII cable and windshield mount
• Customizable digital gauges with multiple layouts and custom alerts
• Data logging, performance tests, and diagnostic trouble code read and clear
• Works with Edge EAS accessories such as EGT probes, pressure and temp sensors, and a backup camera
• Upgrade path to Evolution CTS4 or Insight+ CTS4 without buying a new device
• Fits most 1996+ OBDII vehicles

Specs:

• Display: 5.5 in high-resolution color touchscreen, 60 FPS, auto dimming
• Processor: 1.7 GHz dual-core 64-bit
• Memory: 2 GB LPDDR4 RAM
• Inputs: 5 volt data logging inputs, RCA video input, HDMI data connection
• Updates: built-in Wi-Fi

A great pick for anyone upgrading from an older Insight or adding their first monitor to a work truck or tow rig. Available parameters and features vary by vehicle. Verify fitment for your truck before ordering.
