Crusie being fitted / not fitted is still an option you can view in the BCU, "Maybe" your car is just not enabled for it. Would need to hook it up to a Nanocom or similar to check before you worry to much about other bits affecting it.
my bcu was not enabled when i fitted the switches but it still worked it think urban panzer has a list of people on his website of people with nanocoms who can help could be worth a try
cheers for the ideas but nobody on list in my area wanted it for my holidays on thursday but running out of time, will have to try when i get back thanks again
