Great response ... thanks ... I have been asked by manufacturer to obtain the photos .. I'll advise him of this info.
Maybe there will be someone who makes an AVC version of speed control.
Followed up through those links .. found a link off the 'Tow Mode' which seems to be Volvos speed control, but seems to only accept rpm input .... riders know the speed in mph they want to ride at not the engine rpm .... seems an odd approach.
