I have been working on this most of the day. This "hack" does work, not that I doubted it but in case someone else says it doesnt work, I am here to say it does.
However, I did have some trouble.
For some reason the DVD drive in the car will not read Office Depot brand DVD+R DL disks. Dont know why. After wasting about 10 Office depot disks, and trying two different DL burners, this is the hardware, software and media that worked for me...
LG GSA-E10L External DVD Burner
Verbatim DVD+R DL disks
Nero 7 Software
Burning the Office Depot disks with my dell DL drive, the data would show up on the disk (looking at it with my computer) but the car would simply say "unable to read disk" or Not a valid navigation disk.
This was very frustrating. Hopefully it works for everyone else on your first try.
Thanks a bunch to pillpusher84, his research and efforts have been a huge help.
