How do i burn a Map Disc?

[Mason]

Hi Gents,
Ok I need some help, I have read all the posts on here about burning Nav Map discs (purely for back up purposes only).

Now every time I put the “Burnt” disk in the Nav it says incorrect disc.
The Details:
Nav Comp : Mk4
Nav: SW 4 1/91
2004 BMW X5 4.4
I-Bus
16x9 Colour Screen

Whats on the burnt Disk:
config
db
dbal
tpd
cdrom.tocconfig
db
dbal
tpd
cdrom.toc
files.cfg
INFO_MAP.TXT


How do I burn a copy that works, so far I have (using imgburn) created an ISO file and then burnt it to both a CD and DVD at 1x speed done this about 20 times and nothing.

Any help would be great:

Using Verbatium CD-R and DVD-R
