I use your products "70 mai A400" Please tell me what to do!?
I asked for updates, when I connected to Wi-fi, I updated, but an error occurred, I waited for 20 minutes until a "rollback" occurred - nothing happened. I turned off the car engine, respectively, the power was turned off and it turned off. After that, it never turned on. I read on the forum that you can update the device "directly" via a microSD card. It doesn't help.
