Don't buy!!!!!
After looking at vehicle specific things the carista could do on my car ( checked on there website) the 2 things I wanted were
1) Adding mph on to digital dash
2) Add needle sweep on start
Both of which where shown when selecting make model and year. So I parted with £60 as these 2 things were worthwhile.
Getting the dongle and app and trying to do these 2 things isn't possible. It gives me less info and options then the dongle I got off amazon for £8 and an app from playstore for £3.
Definitely stay away from this product as they don't offer they say they do
