getting the analog clock sync'd with system time
look for the post promising long term fix...... https://mbworld.org/forums/s-class-w...ml#post8574633




The car first looks for the satellite to get its time setting. If you frustrate that, you can set it manually. If you don't do Polarbear's update, your date in the car will always be off even if the time is right.
Good luck.
I was looking at CDs with BenzNinja the other day and we found one strange update CD 2218276259 for a very different head unit (that he felt might be an elusive Japanese model update) and it too runs the same Sat Nav time file - so a brave person could see if they can build a disc for this headunit and copy over the polarbear patch included in what the car believes is update 423
