There is a learning curve on using GPS units, so play around with it and try loading some rides into it that you got off the internet so you can see how to follow a ride that you loaded into it. And try using it for routing where you tell it where you want to go and let it tell you when and where to turn, etc.

I have not used that GPS, I have used other Garmin GPS units. But I am sure it will serve you well, the Garmin GPS units are well built for this sort of thing.

I do not know if that GPS comes with the base maps you can use for both home in UK and Pacific Coast or not. That is a question to ask.
