Not sure if you're still dealing with the stereos or not. The radio on my 2011 Jetta TDI Wagon is doing something I haven't seen on any forum. The display is on, but flickering. But the sat radio won't initialize, and no sound comes from the AM/FM. I haven't pulled the radio to check the back fuse. I did do the 3 minute power hard reboot to no avail. Is this something you've seen before?
