How to unlock a Mercedes radio NTG5 without Vediamo, Xentry and other special equipment, only my simple device.
if you are seller of a Mercedes radio and your buyers does not want or can not go to the workshop, you will send him a radio with my device, he unlocks it himself and gets a bonus video in motion
!!!!!!!!!!!!!!!!!The 25-digit unlock code is absolutely necessary, I do not provide a code, only the unlock option. Only in one case my device can find the code inside the radio, if the radio is new!!!!!!!!!!!!!!!!
