I did it last night and it worked like a charm. I used "Winace" to decompress the files and "Alcohol 120%" to write it to a CD. I already have the Nav. DVD 2006.2 but I will probably try to download and update to 2007.1. The street that my new house is being built on is not on 2006.2 even though the street has been there about a year and a half. Hopefully 2007.1 has it on there.
