Cruise control

[So Cal Joe]

A friend has a Audiovox cruise control on his 08 ST1300, it works great except when he goes on a down grade, it backs off by about 5 mph, holds great on an incline or straight road.  That irritates him so he is looking for a fix or another cruise control. I know that is a couple other units out there one is a Rostra and there is another one I don't remember what it is called but I think someone said it cost around $1,000. Does anyone know the name of that unit or have and idea how he can fix his audiovox unit to maintain a speed on a down grade?

There might not BE a fix.  Cruise control cannot apply brakes (well, actually, it can in my Infiniti G37, but that is not a typical cruise control, it is very integrated, has laser range finders/etc) it can only control the accelerator.  When going down hill in a high gear, there is little to no "engine braking" when letting off the gas.  So the bike might unavoidably gain speed with a cruise control going down hill...
