They are displaying the bars for the signal the car is receiving through its LTE connection. (My iPhone was displaying 4 bars at the time the car was displaying 1 or 0.)
Also, the Lucid failed to switch to the LTE signal when we got out of WiFi range. I had to go into the settings to turn off WiFi, at which point the car switched from the WiFi display to the LTE display. (The techs had had to do the same thing yesterday when they found the car was not automatically switching to a cell signal when out of range of WiFi.)
But we were in the garage with a strong WiFi signal when I was trying to get Alexa to program the nav destination. That was a failing of Alexa. However, we were out of range of the WiFi signal and were not receiving an LTE signal when the nav system failed to give us prompts for upcoming turns. So neither feature was working, each for its own reasons: Alexa because it can't understand voice commands, and the nav system because the car can't pick up cell phone signals.
We've been using nav systems in an array of cars for some years now. I know how to program them both by voice and by manual input in Hondas, Audis, Mercedes, Teslas, Subarus, VWs, etc. So I'm not a Luddite in this matter. The fact is that, right now in our Lucid, both Alexa voice commands and the native nav system are useless.
The address I mentioned earlier that I was trying to load into the nav system was the address of the radar/laser detector installer with whom I had an appointment for him to plan the installation. At one point he needed to check the Owner's Manual for something. Although the car screens had worked on the way up to his shop and continued to work as I took him through some features, as luck would have it, the Pilot Screen froze again just as we tried to open the Owner's Manual. The screen remained frozen even after attempting a soft reset.
At this point, there is no way we would put this car on the road for a significant trip -- something we had been planning to do for some time. Until these issues get fixed, it's a local errand runner only to places we already know how to get to.
