Well I just updated flawlessly with the east file I downloaded via FTP. I'm using a mac so I extracted the iso from the zip file using "Stuffit Expander" to my desktop, then burned it to a FUJIFILM DVD+R DL disc using "Disk Utility". Waited for the disc to verify and eject then took it to my truck, inserted it, watched it update and PRESTO! works like a charm! Haven't really played around with it to see the changes yet but the UI seems a little faster.
