Mercedes Comand NTG3 Clock Fix for S class 221 and CL class 216. 2005 to 2009.
If your analogue clock displays the wrong time and the date defaults back to 2003 (or sometimes 2016) then this is required repair.
We can fix this issue by adding specific software to your Comand system. This will ensure that time and date is automatically set by GPS (and will stay there)
