Did that work as well as their Voicetronic system
The Mercedes S range gets all new tech but it's only when it trickles down to the masses as standard that it becomes truely effective.
It works perfectly on my 2003 SL, ive never tried it on the older S-classes though, but it is the same system so i'd guess it works fine.
The only limitation on the old systems was that they only slow down to as low as 20mph whereby the cruise disengages, this was addressed in the 2006 S-Class which has Distronic 2 featuring proper stop start. This was still a full 9 years ago, this is very old tech now
