I am thinking of purchasing a remote car start for my 2006 Dodge Stratus SXT. I need to find out if I can buy just the Audiovox Prestige APS-57C remote system or if I also need to buy the alarm-bypass module. I was told to go to this website http://www.flashlogic.com/ to find out if I need the bypass but I know nothing about cars. Any help would be great
