How can I fix my Carmin TomTom location?

I have reformatted the card and installed updates but it's still got me located in Wales! 😦
I live in Ireland.
I have put my home location in but that hasnt helped... I'm at a loss now and it's very frustrating.
My car was off the road for 9 months... the TomTom was working up until about 3 weeks ago.
