I tried updating. Let the update run for about 35 minutes. After about 15 minutes the progress bar showed over 4/5ths complete, but then it just sat there like that for the next 20 minutes and never completed. I had to shut the car off then. I went back to try it again. Now there is no database version showing for the current version, but I can still run the update. Again after about 15 minutes it gets to over 4/5ths complete and doesn't progress any further. Do I need to just wait longer, or is there something else I can do?
