Just wanted to jump in and say thanks to @asd255 for helping me out. I made the mistake a couple years ago and bought an update for my 8200 from avicfix (not a good idea). The first time I tried to use the update it did not go well, had a bunch of problems. Not long after I found this webpage and a couple of others and was able to get my unit up and running, but still had problems.
I just recently bought the update to 2018 Q3 on eBay from asd255786, followed instructions that were provided but the update didn't load properly to my head unit. From digging through the files and directory (avicfix's update was causing the problem). I contacted asd255786 and got an immediate response, I was sent an additional file and to retry the update and send logs. It worked perfectly, everything updated and my head unit is now running smoother, quicker and now up to date. Thank you again @asd255.
