brcidd- good info there. I knew it had to do something with security, but this being the first vehicle I've owned with any security type system on it , it is interesting to know the radio has it's own system like this. I've seen the ones on the top of the dash like poncho62 has but thought there were 2 types of systems.So my salesman was only half right, the light is for the radio's security, and not the whole van's .
While we are talking about security systems, my 2006 does not have the light on top of the dash but does have that little red button on the key fob. Is that just a "panic" button and my van does not have a security system like poncho62's? I vaguely remember my salesman going over things with me at the time of the sale an he locked my van with the fob but left the window open on the driver's side. He then reached in and did something which set off the horn. He shut off the horns by hitting the red button. I know every once in awhile I set off the horns by accidentely hitting the red button on the fob while trying to retrieve the fob out of my pocket .
