I finally got mine installed. Was offered to my car about 6 hours after installing 2018.14.2 (I had 10.4 before). Make sure you car is plugged in AND on WiFi. I found that putting the car into/out of drive would kick it off of wifi and stop the download. The download should resume from where it left off when back on wifi and plugged in. (If you're not plugged in, the download will stop after about an hour). And if you're not on WiFi, the download will stop immediately.
Looking at the logs on my car, the new nav sync started at 3pm yesterday. It completed the download at 11:38pm, starting and stopping several times throughout the day. At that point, the new update sat "staged" until 2:45AM this morning, when it started "updating". It looks like it finished updating ("idle") at 9:53AM (which, probably not so coincidentally, was exactly when I finished a drive this AM and plugged it in). I got the new maps notification on the screen when I got back into the car for my next drive a few hours later.
Mine has been plugged in and on wifi all day. Does it have to be charging (I am set to charge after 10)
