Vu+ Duo and Usals set up problem

[silverdale]

I've just changed over image on my Vu+ Duo to the latest black hole and I'm having a few problems with usals set up.
I read this guide and it confused me a bit ;-

"I get the following LON & LAT:
Longitude: -0.1042°
WEST
Latitude: 51.4979°
NORTH

If your longitude is a negative number i.e. it has a "-" sign before the number then you have to subtract that number from 360.

360 - 0.104 = 359.896

So you'd enter 359.896 in your Longitude Settings."

................
My Longitude is ( example ) -002.788
so if I follow the above guide I enter 357.212 ( 360 - 002.788 )

is that right or do I just enter 002.788 in the Longitude box ?

0.104
West

If it is negative value, you enter the modulus and use west instead of the default of east.

so I basically enter ( example ) :-

Longitude west = 002.788

Latitude north = 054.765

?

so I basically enter ( example ) :-

Longitude west = 002.788

Latitude north = 054.765

?

Exactly m8
