I got it too
Mostly because it was £15 at the time.
A few things I've found, this is on a ZTE Blade on roads I mostly know - I've not taken it further afield yet. Overall I like it; I've got used to the TomTom way having had one for years, I'll get used to Copilot eventually.
It can tell you about turns way too early, but you can configure that. I don't think it has variable alert distances based on the road speed like TomTom does.
The routing seems OK. It sent me a slightly odd way to the office when I tested it, but it sent me to the front door so might have been the best way had I not been going to the car park out the back.
It doesn't use the lane guidance arrows enough. I've spotted a few places where it would be handy if you didn't know the road e.g. it's telling you to go straight on, but the inside lane becomes a left-turn lane, so you need to be in the middle lane.
It doesn't stack instructions up like the TomTom does if there are two close together e.g. 'take the first exit at the roundabout THEN turn left'. A few times, Copilot has completely missed the second instruction.
I can't believe Copilot only got automatic recalculation when you go wrong at v9. My TomTom is an ancient Go 500, and that does it.
Why is the UK expensive compared to the US? I also got the US version as I'm off to Boston in August, and that was £6.
