Can you give me the link of the file organisation? I think I can provide another reader for UPIs.... in the next days stay tuned! hi unfortunately I’ve never worked with such files, but I’m investigating on it!

In version 7 of sygic, just renaming the ov2 to upi files works fine, but in the new version 8.06 of sygic doesn't seems to works. I've found this site on sygic http://www.sygic.com/partners/pois.html but not suficient :( Hi, i’m interested too in read/write upi files in java :) .

The function I've provided is only returning dat structures for POI content, reading them one by one (you have to iterate on the FileStream to get all of them). It is only looping inside the OV2 records and if it does not contain a proper POI data field it returns simply a null pointer (to be handled and filtered when the function is called). If you keep looping until the end of the file, skipping the null records, you can retrieve all the POIs of your OV2 File. I've tested with the OV2 file you gave me and it works with it as well. cheers simone I’ve updated the main executing function in my C# code: basically the problem that you were encountering was due to the return values of the read function.

I tried to read it with this code but it throws that exception. I basically had the same code that you have posted in C#, but I always have the same problem, the ov2 file starts with 01, the readOV2Record function doesn't read anything and it returns a null.
