Companion app works exclusively with Rand McNally’s Tire Pressure Monitoring System (TPMS). TPMS hardware includes a Bluetooth-enabled wireless receiver that keeps track of pressure and temperature reported by 4 tire sensors. This app lets you connect the wireless receiver, configure the sensors, set thresholds and receive alerts and notifications. So whether you have low pressure in a tire or a fast leak, TPMS instantly brings it to your attention.

The app also helps you re-configure when you physically swap the tire sensors between two separate tires. And if you lose a tire sensor, the application makes installing a new sensor (available at store.randmcnally.com) a seamless process.
