.Poi extension how to convert

[iammike]

Sorry if this is posted in the wrong forum

A friend of mine gave me .POI file (32 Mb in size) and asked me if I could convert it to .GPX / .CSV (so the extension is .POI)

I tried all programs I know and none of them can convert.

I opened the file with a Hex Editor and it's all "garbage" so no identifiable marks or text.

Anyone know who to open this ?

He said it was made by iGO but I have tried with the utilities and nothing worked.

Thanks in advance

Edit: Another question, are they even "convertable" ?
