I currently have a head unit running android 8 and we suspect it is starting to malfunction as recently the roof has stopped working via the dash buttons (it works when lowered via the key, and can then be put back up via the dash button) and carista is unable to read any dates from the car. My husband thinks the head unit could be flooding the cam bus as it is so old or that it could be a module to operate the roof at low speeds (mine is 2010). Haa anyone experienced any issues like this in the past? What her unit do people recommend as a replacement in case that is the issue?
