Hi all - just a quick note to share my experience. I haven't read through so apologies if this has been covered. Installed the update over the weekend and everything went perfectly, until.............
When the system finished installing the update, the screen said "restarting in 1 second" for about 20 minutes. I turned the key off, started the vehicle again and it booted to a black screen.
Turned off, started again and it came up fine, with new maps and software update.
Just my experience.
