I bought a GPS system for our car back in 2017, but only used it a handful of times. It is a Shenen SAT NAV 7 Inches 8GB Capacitive Car navigation with Touchscreen include Preloaded UK and EU Maps with Lifetime Free Updates. I have found the instruction manual that came with it. However it is in German, but includes photos of the screens and no doubt key terms can be translated.
I am sure it'll still work, but for the last years we have used google maps on my iPhone if it was needed.

Pick up in Cookridge, Leeds
