LTB and L00 file format


Recommended Posts

Lets face it, Avic Feeds is not the best application in the world. I'm a new owner of an X930BT thinking of writing my own application to process these files.

 

I've started to "decrypt" the binary of the LTB (route trace) and L00 (POI) files. I just can't figure out how the longitute and latitude are stored. My coordinates are somewhere around 45.493223 and -73.479733, and in the binary these are stored as 0xfbf6b10d and 0x027fbf79. I've tried many ways but can't come up with the right numbers.

 

Anyone knows?

I do not know, but can give you a clue. Defore I replace map it have shown me somewhere in US. when I replace map from US to Australia it have shown me in ocean first. So I assume it has some kind of relative coordinates for map and POI and shift value somewhere.
