Basically, the card worked in my N-Gage. Unfortunately, there was the call of the MP3 player very often a pesky system errors. If the fault does not appear once, the MP3s are played properly. And yes, the card has been formatted in the N-Gage. An update of the Nokia firmware to 4:03 has brought nothing. There is also positive experience with this card and the N-Gage, the product seems to suffer from quality fluctuations.
