What US state?
I'm sure there are (unfortunately) many people who have been in similar situations. What is your specific question?
I suspect it's Tennessee, and OP is referring to 11/29 sentence for DUI. This is supposed to last 11 months and 29 days, so I guess OP's point is that it's been more than 11 months and 29 days.
If OP has successfully met the terms of probation, then they should go back to court and obtain an order to remove the interlock device.
However, that's just guessing. Perhaps OP will return and clarify.
