We have a 2018 CRV-Ex. We have had intermittent problems with the “head unit” since we bought it in December 2017. Ironically, it has worked very well with my wife's iPhone SE for both Podcasts and as a GPS. Our problems started with the brightness bar self-actuating, darkening and lightening and going black. It has also changed radio stations all by itself. We have taken video of the problems in to our dealer. I learned of TSB 19-066 dated July 21, 2019 applying to ALL 2017-2019 CRV's. A couple of months ago, I took it into the dealer specifically for a TSB fix of the head unit. However, after I sat in the waiting room for a while, the service manager came and informed me that their computer system had been hacked and that the laptops could not complete the update. Later, when I had my state inspection in December, the service manager also was to have the TSB fix done. However, they ended up unable to do it because, reportedly, the fix didn't apply to my car (though the TSB noted above applies to ALL gen V's). We had learned, perhaps on this Owner's website, about pressing and holding the volume button to reboot the system. We have been doing that for almost 2 years. It usually works for a while. Does anybody know about TSB 19-066 and what it allegedly fixes for those who have the right VIN?
