It works fine.
I copied the files off DVD as described in an earlier post, I installed the zone.cfg file I created with all the maps into the DB folder, and BOOM, it worked.
Went one step further , just because I wanted to... first unplug both the CF and SD card...
We are running of external USB drive now! (A LOT SLOWER BOOTING)
Setup... Vehicle position, I choose somewhere in Florida, dunno where...
Note Newmarket is in the back ground before we set the position...
BOOM! We're in Florida!
USB drive FTW!
