I'm the one that started this thread about a week ago.  I appreciate all the input on how to install and other details.
My problem now is more basic.  I live in B.C. Canada and it appears that this unit can not be shipped to Canada, as per Amazon.com. Why? I don't know.
Are there any individuals on this list from Canada that might know of a Canadian supplier of after market cruise controls suitable for a 1990 Westfalia?
In B.C. I phoned Bow Wow auto parts and Lordco but they don't carry after market kits and were unable to suggest a supplier other than Canadian Tire(shudder) maybe.
Thanks everybody for your input on the Audiovox unit.  All I need to do is get my hands on one.
