Hey,

I've been ignoring this issue for quite a while but finally decided to get my hands on it.

Now, here's the problem: head unit display freezes every couple of seconds. It doesn't affect anything (radio, music etc), just display image. During these "freezes" head unit doesn't respond to touches.

Here are the videos:
1. How it looks:

2. I tried changing video sync via diag menu, but noticed that with every "freeze" it changes video sync external/internal on its own. Here's the video:

3. Surprisingly, it's nav screen that works the worst. When in nav mode, screen turns blank for a couple of seconds (which doesn't happen in any other mode).
Here's the video:


Has anyone come across this issue? Any ways to solve it? Will changing head unit help?
