dealer added code alarm, options, opinions?

My dealer had preinstalled Code-Alarms on all of their vehicles. I am not sure what the code-Alarms involve but they use the factory remote and he said it has starter disable. I believe it also has a shock sensor since I accidently set off the horn honking when I moved something in my Envoy the other day. The doors were all shut and had been shut for several hours while I was sleeping at a rest area and then when I hopped up front to the drivers seat it set the alarm off. I also noticed that if I tap my steering wheel the interior lights will come on for a second or two and then shut back off. I will remove this when I install my viper 771XV this week but if it is decent then I will keep it around for another vehicle. Otherwise maybe I will sell it. The dealer was supposed to remove it before I left but they forgot. Anyways, does anybody know what options these have and if they are worth a damn?

If it is a Code system, it would most likely be the CA310. Unless they installed the old ROG-1, but I highly doubt it. Manual for CA310: http://documents.codesystems.com/700886.pdf Manual for ROG-1: http://documents.codesystems.com/701053.pdf
