I have some problem with my radio dab module.
Stuck in one channel.
I think I need a system update
Can you show me the latest infotainment update code?

More likely you just need to reboot it. Hold the physical home button down for about 20 seconds.

No solution with negative battery cable disconnection, factory reset in display o reboot with home button.
i need an update or module replacement
