The device cannot be turned off while the truck is on. Essentially, the Power button will not work until the vehicle is powered down.
The TND™ 760 offers a fleet configurable Personal Conveyance option. The default Driver Setting within the Rand McNally Connect web portal disables Personal Conveyance. Enabling this feature means the in-cab device will record personal use of the vehicle without counting against your Hours of Service.
To enable Personal Conveyance, go to the Management tab on the Rand McNally connect toolbar, click Driver Settings, and then click the Allow Personal Conveyance button.
