2019 June Raven X with 40.50.7 and I also have experienced many bugs with the text messaging but most all voice commands are working for me. HOWEVER, I get random speed changes on cruise or NoA mostly at intersecting over/under passes where there is a different speed posted for the different route than the one I am traveling. Drives me nuts! Occasionally, I get a phantom BRAKE action for no apparent reason, one almost threw me through the front windshield!!! So, they rushed out a buggy update to give us all a Christmas bonus that you kinda have to appreciate that. They will work out the bugs sooner or later. I hope... .
