x1le...thanks for the info, i bought the alarm thinking it was ready to go out of the box, my local car audio shop is the one that informed me i needed that module, what does the module do exactly? he said i need it because the key has a transponder in it. I see the int-sl has a ton of functions, is the module just an easier interface into the car's control systems for all those features, avoids hard wiring?
I bought the 5701 refurbed from gooddeals18.com for $110 shipped, i have been researching now after the fact and i am reading about lots of issues with this model, main one seems to be the two way functionality quits working or never worked at all, functions perfectly only as a one way
im thinking now to send it back for refund and get a crimestopper alarm and their site recommends that int-sl module you talk about, i did not know that those are interchangeable like that between brands.....not sure yet what to do but i have 60 days to return for a full refund
