Car malfunction after connecting RK3188 based head unit

i got my new RK3188 based head unit 3 weeks ago (android 5.1), with CANBUS module to display varies car info in the unit and get the steering wheel controls working, last week my car displayed "Error: Transmission" (Skoda Octavia 2014), and my transmission box started to act weird (skipping gears).
First thing i did - was to remove the head unit, but the problem was still there, as my car is still under manufacturer warranty - i took it to repair shop (after installing the original head unit back), and got it back after four days - they said that the transmission computer has malfunctioned and they replaced it.

The nature of the problem (computer malfunction) and timing of it (two weeks after installing a head unit with CANBUS connectivity) got me worried - that maybe something with the head unit caused this problem.

has anyone every encountered this? can it even happen (is there any protection for such issues in the CANBUS protocol?)?
