i have tried this several times and it doesn't seem to change anything (I am using an iphone). I reached out to their tech support and was told a firmware fix is needed and they are working on it. No ETA was given. I will give them a week before returning it.
I am having the same issue with the screen cutting off on the tbox. I was asked to send in screen shots, which I did. Was told they are working on a firmware fix. Didn't provide an ETA
Experiencing the same issue with the Carlinkit where 1/3 of the screen gets cut-off. Basically renders the device useless, as I can't even enter a wifi password to get it online. So far I am very unimpressed and will likely look to return it.
