Hello KAYUS! Welcome to the Windows 7 Forums website! :ciao:
First of all, how do you expect us to read your mind or know what brand of Bluetooth Peripheral device you have? We're not soothsayers or magicians.
Second, is it a USB plug-in device for your Nokia phone? What brand and what model?
Third, if you bought this device, did it come with a driver install disk?
The more information you can give when posting questions, problems, issues, etc., will greatly help us to respond more accurately and effectively.
Thank You!
