Need Help Finding A Good Alarm System
Thanks,

Now as for the GPS, it is sweet but is a other part all together I think it may work with other alarms as I have seen it! So to answer your question the GPS also needs the alarm part!
I will put in a Viper 2way with GPS when I get the dash back in
Factory alarms usually consist of a relay and 6 wires Ttapped to your ign harness. They are nothing to disable.
