Attention people posting to this thread: This is a thread for discussing software version 2018.39.5. Because it only went to a relatively small number of cars, it is more likely that you mean to discuss 2018.39.6 (or some later version). The thread for 2018.39.6 is here:
Software Update 2018.39.6 8377b4d
Wouldn't it be better to simply change the topic to "Software Update 2018.39.5 and Software Update 2018.39.6"
I don't think anyone knows what the differences even are.
