Route mapping software glitches? The 'Enter Vehicle Dimensions' *should* stop the Garmin from sending you down [too] narrow roads, unless there is no other access, but on 2-3 occasions on our Spanish trip, the Garmin 780 Camper said, e.g., 'Turn left', and then immediately followed up with 'When possible make a U Turn'! And, having learned to ignore these abberations, I also ignore the Satnav's nagging persistence in trying to get me back to taking the original wrong directions ['at the island, take the 5th exit' - i.e. back whence you came]. The falling price of technology probably means that Garmin cannot spend the time required to remove these anomalies, so we have to live with them, and try to remember to ignore the wrong instructions [says me who , in 2024, repeated the 2023 wrong directions on the approach to Vilafrance del Pinedes and took the same 38 mile detour as we did in 2023] ...
Nothing had changed - neither scenery, nor my fading memory!
