3G Exemption Update: The FMCSA has provided Rand McNally a HOS exemption until May 31 for any driver using a Rand McNally 3G DC200 or DC200 Slice. This will provide two additional months to get your units upgraded to 4G capable Vehicle Gateways after T-Mobile begins decommissioning the 3G network April 1. Please reach out to a member of your Rand McNally support team to obtain an exemption letter.  A valid account within the portal will be required to obtain this exemption.  We will also work with you to get your units upgraded to a 4G device by the time the exemption expires.
