I am currently looking at purchasing a SRT9000. I have a 555f pats bypass module currently I was planing on a viper 971xv system. But then I have had a last minute change of heart and want to go with the SRT9000. So I was wondering if the bypass module would work with the SRT9000 or if I will have to purchase yet another one. And would KC autosounds be the best place for me to order from?
