I had a SONY XAV AX5000 AV receiver installed three months ago. This week the radio, gauges, window controls andtrunk control wenot out while I was driving my 2006 SSR. I took the SSR to a local garage that I have used for many years. They saw the issue when I dropped off the SSR. The next morning when they went to diagnosis the problem, it was gone and everything was working. The garage started the error was a buss overload. When the problem occurred the error on the dashboard flashed "Unknown Driver". Has anyone else experienced this issue? Any ideas how to resolve this issue? Everything is working now, but will it return?
