Update on the OBD2 / LELink / Fusion App situation with my RAV4. After many emails with support at Fusion, still no success. So I tried the LELink in my wife's 2013 Matrix and tried to connect to Fusion. It doesn't work with her vehicle either. BUT, the LELink does work in her car with the free LELink OBD2 App. It gives basic readings like tach, engine temp. etc. But neither App works with my RAV4. So there you go. I am planning to return the LELink to Amazon. Perhaps I will try to find a different interface. Maybe not. My impression is that this is a complicated business, and some Apps and interfaces work with some vehicles, but not others. It's not a simple or reliable as it's presented online. It's too bad because it would be great to be able to monitor things like transmission temp. when towing.
