any suggestions on which one to go with?

 

I've got this one:

http://www.autostart.ca/prodInfo.php...0&prod=AS-1775

It's got pretty good distance for the start and it works relaibly, the only complaint I have is that while it will lock and unlock the doors, it won't do them the way the GM keyfob does - implenting the horn honk option.

I'm told it's tough to integrate these things into the existing GM security setup.

 

I've got the Viper system that I can operate w/ my iPhone. Remote start has impressive range with the Viper fob and being able to open it with my phone is great, particularly when my wife needs something and I'm two time zones away.

 

Mine came installed with an Auto Mate from the dealer. It works great has good distance and works just like the factory fobs.

 

Well, apparently my car starter installer were fibbing a bit to cover thier lack of skill.

That Viper system sounds awesome.
