Having trouble using Waze navigation while in my 2018 XE. Setting and using Waze on my Iphone in the house or outside is fine. When I enter the car I loose the voice for my Waze app. Spent close to an hour with a tech. when I picked up the car. My 70 year old eyes glazed over while he was showing me all the features of the infotainment system,I forgot to include Waze. Before I make an appointment and go back to see him does anyone have some advice? The Jaguar navigation is 70% at best for speed and accuracy so I like to use the Waze as a back-up. Jack
