Well, I wasn't going to go into detail on that, but since you brought it up...

I had the Omega system removed and a Viper 330V installed at a local authorized Viper dealer/installer. The 330V just takes a factory system and augments it. It uses the factory transmitters. Basically, I'm fine with the factory system, but would like something to add the following functionality:

• Horn chirp when arming & disarming
• Starter kill when armed
• Automatic lock/unlock with ignition

The Viper 330V does 2 of those 3 things; it doesn't do the horn chirp. The only thing it will chirp is the Viper siren if you get it installed, which I didn't. Odd as this may sound, I didn't want the rest of the functionality of the system, i.e. the alarm part. Unfortunately, I discovered after I had left the dealer and they were closed for the day that something is wrong with the interaction between the Viper and factory systems: Whenever you arm, the alarm goes off right away. Weird! So for now, I am just running with the Viper system in valet mode, which still does the door lock/unlock but nothing else.

I'm probably just going to have it removed, since it doesn't really provide any extra functionality that the factory system doesn't, except for the automatic door lock/unlock, and to me, that's not worth the $200 for the system.
