07 S550: GPS time issue
Posted: Mon Nov 15, 2021 8:52 am
My clock and date were way off when I bought the car. I was able to set them with no problem but it appears this car is afflicted with the same GPS time rollover issue as my STS was!

The fix is the same. Just burn the updated firmware to a CD and load it into the system. I guess I'll put this on the list.
Matches.

Sigh. I better check that.before trying again I would check your comand menus to see if the sat nav has the menu for the Birdseye mapping. the author of the file mentions he thinks the "clock patch" may not load if the car telematics ring is running old software.
you may need to update the car then apply the clock fix. The interesting point here is Merc adopted the fix so ought to make a new all in one update disc (but I doubt they did). NOTE: Telematics update (on pre 2008 MY cars) done by the dealer turns off the AC pump and they need to go back in and tick a box to re enable after the update
