me too on 4.1 (1.19.31) for many days, no issues. and i note, knock on wood, i have not had to reboot any systems at all so far since taking delivery. on ONE occasion i did have an instance of turn signal not dinging, and the radio audio cut out for a second as well, but it fixed itself after couple seconds. we are driving a computer after all. it's not gonna be totally bug free just yet. some of these things that people are 'rebooting' displays for i feel are simply sub-systems taking a second to wake up and login to the data gateway in the car, so the temp setting and things like that will probably fix themselves after a minute or two.
i agree these little glitches shouldn't happen, but i for one, as an avid tmc reader as we all are, would appreciate a little less hysteria (not pointed at anyone in particular, just in general) about things when reporting them. some things, like stranded at a snowy roadside with dead 12v, yes, get slightly hysterical, seems warranted. things like no temp readout or momentarily absent sound fx... well, can we just keep a little perspective? by all means report it, and i do wish tm had a bug reporter system in place so they can be compiling all these events and sifting for important ones and persistent ones and the like, but maybe we can keep a little calmitude in relaying info to the group about our experiences with the car/software as we go. i'm getting to the point where i don't read certain threads anymore because people are posting the same freaked out posts over and over and the actual flow of information and meaningful discussion is near zero at times... AGAIN, not in any way directed at any post/poster in particular, or even this thread in particular (it just occurred to me again here, so i mention it.)
hopefully tm is working on a direct, simple, bug/issue reporting system that will enable all of us to feel confident that the powers that be have the feedback they can use to keep making the car better and better, and we won't feel the need to howl into the tmc wind quite as much.
