I (try to) use it on my 2020 RC f sport.When it is working it can be quite useful..shows you the current location of your car, sometimes,sometimes it tells you it's 10 miles away when you can see it on the drive.It tells you the current mileage reading,but never accurately (within 1-200 miles).
It shows the charge level of the 12v battery--red or green.It tells you you've had an accident when some stupid woman drives into the back of you and documents the time,location very accurately and its own classification of the severity of impact.
Your service history is on there as well.
Unfortunately,it doesn't always work.mine is currently stuck on 15 June.Worth a try ,though
