I am having a very worrying issue with my Bluetooth headset mw600, which I have recently bought to make use with my new Sony Ericsson Xperia active. But however it fails to display tags and also it is not fully compatible with the Xperia active. I have tried many thing and tricks but however I canít able to make use of this Bluetooth handset properly with my Mobile phone. So if you guys have any of the information about this thing then please let me know. Any of the reply or the suggestion will be appreciated.
