The evo-one will remote start your vehicle, however the T11 is not 100% compatible with the evo-one, hence why we do not list that remote in the RF kit section of the fortin website.
If you are set on getting the T-11 the following items is what would be required:
1- T11 remotes (firstech product)
2- T11 compatible remote starter (first tech/Compustar)
3- INT-SL+ (This is the bypass module. This would be the guide for the bypass portion of the installation, you would follow connection 3: http://cdn02.fortin.ca/download/46281/int-sl+_revj.pdf)
Also please note our solution only works on the standard metal blade key version of the 2006 cts. Not compatible with the smart key version.
