Driving to Bridlington the Sat Nav suddenly went off piste and is now showing the car in the middle of nowhere.

I have rather optimistically disconnected the battery for a few minutes with no change.

Everything else works fine.

I have wrecked the system data and it shows no satellites and no height above sea level so I suspect the aerial has failed?

Does anyone have any similar experience sand mor importantly how easy is it to check the aerial replace it if it is faulty and any idea of cost?

Thanking you in advance for your replies.
