Oh, drat. It looks like I really should be able to drive. For some reason, after reading the link, it unnerves me that I'll be tested on a sat-nav. I'd never own one, but.... they give me the willies.
So, hmmm. How does one find a good driving instructor? Does the driving school have insurance to cover the learner and the car during the lessons, or do you have to get your own insurance? What should a driving school charge?
I Googled and found a few instructors. I just tried them out until I found one that suited my needs. The first was terrible with the US/UK switch and obviously didn't know what I needed help on. The second was perfect. He knew I didn't need to be taught to drive, just taught to pass the test and get used to UK roads and driving styles.
The instructor should have insurance covering you in their car.
The sat nav will only be a small part of the exam and I'm sure instructors will start teaching it in lessons, especially if you're uncomfortable with it.
I'd suggested either taking the test before the changes (although that's be really rushed) or a few months after it rolls out. That way you wouldn't be the guinea pig.
I'd also try to avoid winter for the driving test. Snow, ice and short days are just one more thing to make a test more stressful.
