I followed the instructions on this page, but the unit didn't give me the prompts that the website said it would. It just asked me if I wanted to update to version 1.400 and I clicked yes. At that point, the unit just went into the SI screen and has been there for 10 minutes. I'm scared to do anything because i'm afraid it will mess something up. It never asked me what Steps 5 and 6 said it would. Please help.
