That is why I put it as a new thread to find easier.
Thanks so much I have tried everything and spent hours but none of my computers would see my nuvii anymore. So of course I could notb get garmin express to connect. Changed to mass storage and connected immediately. Why on earth is such an important setting hidden away. Whay hasn't Garmin got this solution in a more prominent place. How many people have had to buy a new satnav because of this. Maybe i have answered my own question.
