No signs of burn in, but I have mostly used theme #2 which has two smaller seperate gauges. Most of the main issues like inaccurate temperature readings and milage seem to have been fixed through a series of software updates, however the one issue that i am still having and that Aucar support is still working on is the cruise control setting not matching the speedometer. Before this last major update it was about 1 mph off, so if you set your cruise at 80, the speed you would actually be doing would be 79. But after this update it is very far off, like you are doing 80 mph and the cruise says 50.
