Still not Mexican.
I think I may have "blown" my factory head unit installing the Sony bluetooth. If I go borrow a friends head unit and put it in my car do I need a security key or will it just come one. I am trying to determine what went wrong. I figure if someone elses head unit works in my car I will no that is the problem. One stupid mistake I made was cutting off the factory BT connector, all six wire simultaniously, without disconecting the battery. Now the security light on the radio is not even blinking. HELP!!!
