I was just wondering what kind of alarm system was in the EXT. ALso with the recent post of getting your ext stolen I was wondering if anybody knew how well they worked. I figure that in a 60k car that the alarm system would hafta be somewhat decent. Let me know and thanx for the help.

I did an extensive search on your 04' EXT alarm system but no information on your alarm was found. I would call your local Cadillac dealer and talk to someone in Service and ask them what features your system offers. Ask them if it has GPS tracking, if it doesn't i would upgrade your current alarm.
If you are interested in a GPS system you can e-mail me.
