Rally Comp

The Rally Comp device provides timing, scoring, pass alert, live position track, and and navigation functions


A Rally Comp device is required for all competitors, including cars, UTVs, and motos.


The Rally Comp device will be supplied to competitors at Registration and MUST be used through the full rally.


Competitors MUST utilize the power cable connected to the vehicle 12V battery to power the Rally Comp. All cables for the Rally Comp will be provided with the Rally Comp device. The power cable MUST be wired through a fuse then directly to your vehicle 12V battery rather than through a cigarette lighter socket or similar ignition key controlled power source. If the power to the Rally Comp is interrupted, such as when you shut your vehicle off, it will take longer when powering back up before it is able to perform its functions due to requiring a good GPS lock.


The Rally Comp supports several mounting options, RAM mount, ICO type two stud mount (fits in a traditional ICO position for motos), or other arrangement using some type of bracket attached to the two rear bolt studs.


The newer live position tracking antenna module is not shown except in the View and Dimensions image.


See official Rally Comp info for additional details.

Rally Comp Video Demonstration


This video gives a general overview of the functionality of the Rally Comp. For Sonora Rally the roadbook scroll shown will not be used, as motos will have their own full-size roadbook holders, and cars have navigators to hold and flip through the roadbook pages. For Sonora Rally a few functions shown in this video will not be enabled, or will operate in a slightly different way, though the concepts are similar. The display readability has been improved since this video, so there should not be any issues with that even in the darker environment inside a car. We will publish details instructions on how to use the Rally Comp at a later date. For the most part, you should be able to race the whole day without pushing many buttons on the Rally Comp. It does its thing without much if any user intervention.
