W164 Time Adjustment

[motorman3]

My imported 2007 ML63 is equipped with an aftermarket head unit, hence lacking the COMAND system or any other Mercedes head unit. The steering wheel controls are nonfunctional, perhaps due to the incompetence of the individual who fitted the head unit, which suggests that resetting the clock is also not feasible.

The analogue clock functions properly and maintains accurate time; nevertheless, it is somewhat more than two hours slow. The clock is not independently fused, and unless the iCarsoft MB2 can reset it, which to my knowledge it cannot, the sole remedy I can propose is to remove the instrument cluster fuse (No. 11 in the dashboard fuse box) and rejoin it ten hours later at the time indicated on the clock. Does anyone possess alternative suggestions?

As I recall from the installation on my W211, it necessitated utilising STAR to inform the vehicle that it no longer possessed a COMAND unit (i.e., configured to Audio20 or a comparable system). The menus were reorganised to make the clock setting accessible in the dashboard cluster, instead of being configured using COMAND.

To connect the steering wheel controls, an interface box is required to facilitate communication between the steering wheel and the head unit.

I appreciate that. The owner's manual does not specify a manual setup technique; nonetheless, I will investigate further now that I am aware it is possible. Salutations.


I am aware of the MOST connector box; I simply have not attended to it yet. It is not an issue.

This vehicle lacks a mechanism to reset the clock via the instrument cluster; the only modifications available in the 'Settings' menu of the instrument cluster display are the digital speed display, odometer units (mph or kph), and language selection.

The fuse is now blown, and my phone is programmed to alert me just prior to the need for replacement. I remain hopeful that it will succeed, as I perceive no rationale for its failure.

It was successful on the third attempt. Upon removal and reinsertion of the fuse, it resets to 12 o'clock rather than resuming from its previous position (first attempt...). It accomplishes this by rotating the hands the longer distance from their previous position to 12 o'clock, rather than the shorter route. It surpasses 12 o'clock, reverting to approximately 10:45 before returning to 12 o'clock (third attempt...). It is now approximately one minute behind, but life is too brief, and I lack the motivation to address it.
