Hello together, since about 1 week my infotainment in the Volvo from time to time passed the function. Hot lighting and e.g. radio worked but you could not set anything more, operated. After about 2 days everything was dark, like if there is no power on it, the steering wheel operation, e.g. for Navi also does not work. Today the lighting again burns but otherwise nothing comes on the display. Also an operation is not possible. fuses exchanged, they were, it is not. i Volvo to ask if the problem is known to remedy it. Statement no, you have to go to troubleshooting. I’d like to look at it myself first, someone has a tip for me. A guide on what I need to expand where to check. Would be great.
