I can not help you about Bitmaps, I have only been looking into the alerts in poi.
Its been a wile since I looked into it, and have many unsorted papers .
I have a picture here of Hex, dont know if it helps you.
This is only what i experience, and I my be wrong and my memory could be failing.:
[Only registered and activated users can see links. ]
A blue line divide the picture in 3 parts: Header-poi nr1-poi nr2
Blue :coordinates
Yellow: Text
2 byte,Inside Red line/white:Proximity
2 byte,Inside Green line/white:Speed
1 byte,Inside Blue line/white :Alert on(01), of (00)
1 byte, black line/white: Type of alert (00 360° alert)(01 Along road)(02 TourGuide) This file is manupulated and shows 04.
1 byte ,dark blue line/white: Custom sound nr/ if no custom sound: 00=Beep/01 Tone/02 3 beep/03 silence/04 Plung/05 dobbel plung.
Alert part in poi start with: 03 00 00 00 0c
Blue line/Pink: Offset of the code, and the code.(this is an PoiLoader file, so its not coded, just to show)
Brown: Length of text (how many byte)

@Vestenfjell
That will keep me Busy for a While.
Managed to look at a few fields already.
I have this string in Hex for the Coordinates. 7c be 54 ed 0b 4b 0f 15
Can you help me to decode it please.

Thanks
Regards.

32 bit:7c be 54 ed = ed 54 be 7c =deci 3981753980/11930464,71=333,7467631635952-360 = -26.253268 decimal degree (South and west is minus 360 )
0b 4b 0f 15=15 0f 4b 0b=353323787/11930464,71=29.615150 decimal degree
It is in a road R38 in South Africa, does it seem right?

Correct Decoding the location is Exact.
Tonight I'm going to attempt some of my own decoding, Suspected that I had to reverse the numbers.
Thanks for Everything so far.

There is 2 byte code. And it is not encrypted it is packed only.
I ask for this instrument also many times. Someone can do it! For example PIGTones decrypted voice - it is usual vpm but two times less...
