Hi everyone! From time to time, my radio-satnav unit doesn't switch on. After I brake a circuit (take out fuse and put back, or disconnect battery for charging) comes back, but after couple of days of using it's start all over again. Does somebody have had a sam issue? What could be a faulty- need to be changed?
 
Welcome.

One commonly overlooked issue is that the round volume knob in the centre of the infotainment system is also an on/off power switch.

If pressed, it will switch off the infotainment system. Power cycling it by pulling the fuse will switch it back on... or you could just press the volume button again :D

It is possible for this button to get accidentally pressed while driving.

Obviously, there may be a different issue with your system, but I would check this first 👍

Many thanks, it's not the switch, already tested. The infotainment doesn't get power, but after fuse puling out/put back it's turn back to live, and I can switch it on/off by powerswitch.

Is the fuse sitting firmly in the fuse holder? Have you tried changing the fuse? (Sorry if it's obvious, but it could be something that simple)
 
Wot, no Basil jokes being offered up.....?😉
