Navigation problems

[eyemdee]

Does anyone else get incorrect instructions from their Navigation system when there are roadworks in the area? I have a 2019 Corolla Design with 2020v2 map update and it seems to be worse then ever. I came back from the East Coast yesterday and it kept trying to send me on roundabout diversions in the wrong direction. Roads kept showing as blocked when they weren't and I got constant "perform a U turn where possible" commands. On the way there, 2 days previously it kept trying to divert me from the A46 Lincoln bypass into the centre of Lincoln, even when I was well past the centre and approaching the A158 to Skegness! I have had the odd problem before but never as bad as this. Can anyone throw any light on it please?

Hi do you know what preferences you have set for the navigation? There is fastest, shortest & ecological. Have a look at page 98 of the nav manual. You can also have "avoids" though I guess you'd have to set them yourself so you'd know See pages 79 onwards. 

I had a Nav issue & took it to the dealer. They loaded new maps & software, that might be an option, though you may be up to date . My problem had the car being shown as driving in the opposite direction to what it was, the Nav told me to do a u turn about half a mile into the English Channel! 

Good luck
