Do any of you have the factory upgrade alarm with the remote start? For those of you that do, are you happy with its performance? What does it do different from the regular alarm? :feedback

I do not have one - but here is a link to compare prices -> http://www.powercallsirens.com/fso.htm

I believe the DA Gold is the factory alarm.

Any one else? :feedback

There really isn't much you can do w/ upgrading the Factory Alarm to anything... QuikLS gave the website of the upgrades that are specific that lincoln uses...

Other than that, you'll have to go w/ aftermarket.
