After four frustrating weeks of ownership I took my wagoneer for a drive this morning and everything worked. The guys in Ontario Canada must have had a busy weekend. I've had start/stop issues, poor apple CarPlay connectivity, unstable navigation and no weather. The screen seemed much more responsive and the TomTom navigation was showing information. The weather app responded with a great detailed map and conditions. I didn't notice a start/stop notification so when it stopped at the first intersection I thought I was joining the bad battery club. Now I just have to remember to disable that function. I was almost ready to start shopping for another Denali but now there is hope. My next step will be to get some bluetooth headphones and learn how to utilize the entertainment screens. This is probably going to be a pretty amazing car once all of the functions work.
