Remember where you've been.

Nexus records where the vehicle was parked, so you won't have trouble finding it again, and keeps a history of previous drives.

Then understand the drive.

Nexus builds a detailed report for every trip — distance, drive time, speed trace, and a drive score — so you can see what's causing your fuel efficiency to drop before it becomes a problem.

Diagnostics

Know what's wrong.

Nexus runs deep diagnostic scans, including mode 6, to help pinpoint issues before you take the car to the shop — checked against a constantly updated database of thousands of DTC codes.

CAN Opener Hardware

The hardware disappears.That's the point.

CAN Opener sits between the vehicle and the software layer, turning automotive networks into connectivity modern applications can use. It comes in three tiers — Standard, Premium, and Pro — each opening up more of the vehicle.

Cars were built with networks.We're building what comes after.
