Assalam o alaikum,
Recently I had some battery terminal cleaning done because it had sulphate all over it and due to which it started flashing 'Check Engine' light. So the battery was taken off and afterwards, not sure why, the navigation system (NSDN W60) locked itself completely. And now it only shows keypad with lots of characters mostly in Japanese and no button on the panel works. The front panel doesn't even open up to let me remove or insert the SD card.
I bought Mira Custom year ago without any unlocking code so I am completely clueless at the moment as to what I need to do and I can't find any help on the Internet as well, I would appreciate any advice / suggestion in this regard from anyone who might have run into similar issue and was able to unlock the system. I am even willing to pay for any help provided in this regard.
I have attached the image that shows how the navigation system looks like.
Regards
Khurram
