It is very easy to turn on. The dealer would not turn it on. They ever said it could not be turned on.
I purchased a Durametric Professional cable. Plugged it in with my lap top went the to control panel settings and turned it on. It was that easy.
Durameteric has 2 different cables.
One is the Enthusiasts Version which will allow you to do 2 cars. (it must store the ID's) That version allows you to turn on the OBC so you can add that stack but it dies not allow you to turn on the Cruise Control.
The Professional version lets you do unlimited cars and you can turn on the OBC and the Cruise Control.
I bought the enthusiast one first but when I found out about cruise control they gladly took it back for a full refund and I bought the pro version. Now I just have to buy the stack of 4 switched, do the wiring and I got all the features I want for my Boxster S.
The Durameteric also give you full diagnostics so it is well worth it.
