Perhaps this will be a start, rather than a full tutorial.
The 2013 CT200h that I bought is great with low mileage. I have mastered most of the uses of the car’s many buttons, knobs etc. However the Quick Guide book covers the Satnav in a brief sort of way. The main owners book just says refer to the navigation system owners book. No room in my Lexus leather folder for anything looking like that.
So using the menu doesn’t cover how to put in a home route. It still has in it the old owner’s routes and nowhere can I find How to delete them. YouTube hasn’t helped so far but rest assured if I come up with anything I will add to this post.
