Thanks for the answers. I appreciate it.
Mission accomplished!!!
I upgraded successfully to the latest 3.4 with F13 maps. For now I didn’t see any casual reboot even with a wireless device to connect the smartphone to Android auto. For now I can say it ‘s like driving another car. Every function is better, now I can even use the navigator and the vocal commands, before it was useless. And everything is faster.
I don’t want to speak to early but I think I solved the reboot problem.
I’m going to test it in the next weeks.
Thanks again for the answers.
Thanks for the feedback, glad you have it resolved. Enjoy your new car!
