Yeah. My bad with the post #513, got myself mixed up. Edited now!
I could pay £50 more and get the viper alarm fitted too. But not sure, part of me is still worried that it will all happen again as its not 100% sure what caused it all with SLAM, though it all points to the Dastek but the problems didnt happen until after the alarm was fitted. Least if I just get the central locking fitted I know its not going to happen at all.
