Setting Up with the IROAD OBD-II Cable

A Simple Alternative to the Traditional Hardwire Installation Method

Setting Up with the IROAD OBD-II Cable

The IROAD OBD cable allows IROAD dash cams to be connected to the vehicle’s OBD port and still offer parking-mode recording with voltage cutoff protection. This eliminates the need for a traditional hardwire method to the vehicle’s fusebox using a traditional hardwiring kit or via a dash cam battery pack.

OBD ports in vehicles are typically much more accessible and easier to install, thus making this a true plug-and-play system. Simply find your vehicle’s OBD port and connect the IROAD OBD cable. The most common places for OBD ports in a vehicle is to the left of the steering wheel and underneath the dashboard. There may be a latch or cover that you need to remove/lift in order to access the port.

Voltage Cut-off Settings

After connecting the OBD cable, the voltage cutoff settings can be adjusted in the IROAD viewer or the IROAD smartphone app. The voltage cutoff levels are:

  • 11.3V
  • 11.5V
  • 11.8V
  • 12.0V
  • 12.3V

For most vehicles, 12.0V should provide about 6-8 hours of power after the car turns off and still offers enough juice for the vehicle to start up again. During very cold weather, we recommend setting this to 12.3V.

Standard or Parking?

The IROAD OBD cable has two switches on its side - “S”, which stands for Standard, and “P”, which stands for Parking. Having this in the S position will mean that power will cut off when the car is off, and setting this to the P position will allow the OBD cable to continue drawing power when the vehicle is off.

Thus, if parking-mode recording is desired, simply leave this to the P position. The voltage and timer cutoff settings can all be adjusted in the IROAD viewer or IROAD smartphone app. We currently sell two versions of the IROAD OBD-II Cable, one for electric/hybrid vehicles, and the other for non-electric vehicles.
