No problem with the download. Uncompressed the .rar file with TugZIP as recommended by Ucrew. Then used Alcohol120 to burn the image onto a CD-R using the slowest speed....which was 4X on my CD burner.

Did the usual upgrade....put the key in position 1, press accept, eject the Map DVD from the drive....put in the CD with V27 OS in it....then let it upgrade....the screen will go blank for about 5-10 seconds, then you'll see the upgrade screen....upgrading software.....then it will pop out the CD on its own....you should remove the CD....go back in the car and press "OK" to reboot the NAV system....when it is loaded up, then put back in your DVD Map disk.

Then press "Menu"....go to Setting....if you see SW 4-1/70, then you have V27 loaded up....However, now you'll have to hold on the MENU button for about 5-10 seconds....now you are in the "service menu" and using the right knob and turn it all the way to the bottom (it will scroll) and you'll see "Perspective"....select it and turn it on and then hit your MENU button to escape.

Now, you can go select "Perspective" in the Map positioning option.


Again, thanks to xoutpost.com!
