THis was alpine's best and probably one of the best alarms out on the market at that time. It has been killed-off just over a year now. Check out some of the alpine dealers on line, if that fails try alpine warehouse, in the us, just go through their site to get the info,

other then that you might be sol, sorry. But you can use the 1005s fetures and transpose them into another unit, like a cifford or dei. But they will have to the top models, b/c of the option availibility. When doing this all you need to know is the signal out put and use the right input (matching), from the alarm.
