Help with solving a sat nav glitch

Thanks for trying, I’m a little confused when you say router. If you are wondering about my setup
My old smartphone with no SIM runs from MIfi router

One thought on my destination, Camborne Retail Park

Was probably why sat nav wanted to take me back to the 'slip road roundabout (Avers) then down the A30 and off at Tolvadon.

Again thanks for trying, next time I’m that way ill give it another go.
