Adding auto start to Viper 350HV

How can I get the part to add remote start to a previously existing alarm if the guys at the audio store say they can’t get the part b/c they’re lame?

I need it for a christmas present - please help! I know it’s an available add-on, I made sure when it was purchased. :cross:

link www.dei.com I think DEI, [Viper] still makes the Your Valet an add on remote start, for auto. trans. only. :danger 94
