I have a comand that I installed in my 2006 w203 C230 SS and the date on the comand is October 2007. I have got it completely installed and I am not able to set the time zone on this unit. The time button is not available. It is not highlighted in the system menu. Does anyone know what might be causing this? Do I need to take it to the dealer to get it hooked up to the Star Diangnotic. The GPS is working fine and functioning, but the time is off by an hour. I have searched the forum and have not found to much on this issue. Thanks.
