Yes, I had an occasion where the voice guidance told me to go left where the main road I was on actually went straight on with only the slightest deviation to the left at the junction. Lane guidance? As for urban streets, I have seen a lot of Cardiff back streets which I would never had experienced if it were not for the nav system! The motorway exit view (with the signs etc.) appears to only be displayed if you turn off the automatic zoom on the map as a junction is approached. Switching the zoom off also enables the pop-up local route screen which is disabled in preference to the zoom. One amusing feature is that if a motorway junction is signed with "Services" as the first entry on the sign then the voice announcement gives this instead of direction to an actual place.

Although I have a RX450h with the high end navigation system, I have had exactly the same experience on a recent trip to Bristol and Cardiff. The peculiar choice of routes (via town centres when simpler bypass roads are available) and direction down dead ends certainly rings a bell with me. It seems particularly poor in cities as I was told to go right round roundabouts to U-turn on several occasions. I checked the maps issued with the car (which was new in September 2016) and these are dated October 2015. I complained to my dealer who has confirmed that new cars being sold today also have these 15 month old maps. I don't think this is good enough for this level of vehicle.
