Video showing one of the 3 ways to access the Service Menu inside Toyota and Lexus Gen 5 Nav Systems. The service menu includes the GPS Override option. Be safe - only use this when a passenger can safely input addresses or phone numbers. The service menu contains other options that should only be used by a Lexus or Toyota service professional. Do not attempt to access the service menu if you are not a Lexus or Toyota service professional.
