need manual for audiovox asgm4

Hi....We are getting my dad's car ready to sell and we need the instruction/installation manual for the Audiovox ASGM4.  It seems the garage disabled it the last time he got it inspected and we want to make sure it is in working order before we sell it.  Any help would be appreciated.

Audiovox is a very customer friendly company, they have most of their manuals on their techservices.audiovox.com website, it's free to sign up and access. The model number you have listed however is the model number of the bypass used for GM vehicles. Follow the harness back from the unit you found and you should find the brain of the remote start itself. Then head to the manuals section of the Audiovox site to get what you need.Installer, IT support, and FFL. I need less hobbies.
