Yup, that's my experience as well. Nowadays, I hardly ever use Lucid's navigation. It is basically useless.
A few days ago, I was trying to find Costco in Concorde CA. Since I've never been to Concorde (driving from Sausalito), I needed navigation. My phone mount in my AGT is at a place I can't see the screen very well. So, I thought I will give Lucid navigation another go. It routed me all over the map! I finally had to stop, pulled off the Hwy (I-680), and restart from scratch, with my phone (Google maps).
To my knowledge, Lucid's navigation uses HERE maps, a European vendor. The routing can be very funky. Also, there is an unacceptable amount of delay. If you missed a turn, by the time the navigation re-routes you, you've already missed the new turn.
