Not sure if this should be under a separate heading but as I mentioned it here.
Carista dongle procedure, it all went to plan but some differences.
The dongle is available on Amazon at a discount price but not obvious.
Sellers mention Carista Gen 1 & 2, don't get hung up on this, they are and do the same thing, the confusion caused is all about packaging.
While you do get a free 1 months trial, you do have to purchase a full years subscription and cancel within 30 days.
In the UK once the app has downloaded, dongle plugged in and both phone and dongle are connected, there is no longer a choice of countries as stated in some of the You Tubes,
This I think is because the Carista app has evolved/updated, you get a choice of Germany, Europe/Other, choose the latter if in the UK. There is no Australia or America selection although there is still the choice of languages
Depending on what you are attempting, the video/s are pretty much as advised.
I got my big speedo back so am happy. 😄
