With the sample line you show:
$GPRMB,A,0.00,L,,SIGULD,5708.612,N,02450.922,E,25.760,61.5,,V,A*74
that code will put "L,," in Navigate, right?

Yes , will put "L,," in Navigate !!! :)

That's probably not what you want, since the "L" and the following two
fields aren't related. Why Dim Navigate (1 to 3)?
According to Dale, RMB looks like:
$GPRMB,A,0.66,L,003,004,4917.24,N,12309.57,W,001.3,052.5,000.5,V*20
where
RMB Recommended minimum navigation information
A Data status A = OK, V = Void (warning)
0.66,L Cross-track error (nautical miles), steer L or R
003 Origin waypoint ID
004 Destination waypoint ID
.... etc.
but your sample is:
$GPRMB,A,0.00,L,,SIGULD,5708.612,N,02450.922,E,25.760,61.5,,V,A*74
so you don't have an Origin waypoint ID from your device.
If all you want from that part of the sentence is the steer direction, I
would get the data this way:
call getValidity
call SkipCommas(2) 'ignore Crosstrack error
call GetBytes(Navigate,1) 'Steer
call SkipCommas(2) 'ignore Origin Waypoint ID
