I did try a full factory reset, this unbound the car. I then rebound it ( the binding was successful) but the problem of the car not responding in iSMART remained.
The things I have tried (some of them multiple times) are:
1. Unbind from the app and rebind
2. Factory reset of the car in settings and then full set up.
3. Remove the battery negative lead for 30 seconds, then reconnect and setup (note that lots of systems appeared to fail after the battery was reconnected. They did recover after a short drive).
4. Hard reset of iphone
5. Delete and reinstall the app
6. Checked the internet connection in the car, which appears to work (proven by streaming from Amazon music, while the phone was not connected to the car)
I believe the telecommunication module has failed in the car, I come to this conclusion because in System, the “Telecommunication version” is blank and it used to read “1.04.001.z02”. Also, and I am aware that FOTA is not available, but, before when selecting “update”, it read “no updates found” or something similar, now it shows “other exceptions, please try again”
Has anyone else found that the telecommunication version is blank in settings?
I am contacting the dealership and will probably have to take the car to be fixed, I will update once I have a solution.
