“Can i register MDR-ZX770BT for global Sony support ? purchased on 20 feb 2016 from Best Buy, USA; however we live in USA as well as India. Tried to register through productregistration.sony.com Not Sony simple, easy and friendly - even after giving best buy purchase date and email id. Registration accepts only USA zone like 95051 and does not accept other countries although lead to a list of countries. Then it asks password and confirm password- best buy password, new password - all show error !?”
