Thanks for the answers, guys!
I live in Hungary and I recently bought this phase1, which is originally french, this is why its speaking in french to me. :D
Back to the problem...
In the meantime I figured out, that the "beeper" in the lower trim level cars is a relay-like thing located under the fuse board.
My RT trim car didn't have one of those, because it should warn me by voice (i think..). I installed one, and its beeping nicely now.
Does your cars warn you when the ignition is OFF, lights are ON and you open the door?
Because I can't get mine to warn me, or to repeat what it said..
Thanks!
