SUNAVI Navigation software Maps Software

I bought a new phone recently and on it was some navigation software from Sunavi. Actually, I do not expect to use it much, but then again… It looks nice but unfortunately the only maps that were installed were  “British”, “France”, “Italy”, “Portugal” and “Spain” and obviously I live in the Netherlands.

After some searching I first tried the main home page of the supplier of the GPS Software, ““, but it looked a bit disappointing. There are more spelling mistakes on this website than I have ever seen before and although the main website promises access to all downloads for free once you register for the forums… the download area is empty and the forum contains 11 postings of people looking for a map…


So that got me even more interested :)

When I look on the storage media itself I find the folder \SunaviMapData\MAPS and in it  are (1) the maps (.DB files), (2) Signature files containing some kind of hashed key and (3) “” + excel file that is probably used to to generate the file.


Editing the MultiMap.Tab file is not much of a problem, I can just uncomment the #OPTION for the Netherlands :


The DB file for the Netherlands I could find via a forum I found on the Internet: but… I don’t know if these match my version of the software.

But… now I still need the NETHERLANDS_HUAJING-CHINA.SIG file to make it work and that is a bit of a problem: how do I get the signature file?

Let’s mail Sunavi first before I start creating sig files.

update 1:

I got the following reply from the mailserver of the company :
