It’s not really a problem to install an acustic confirmation when unplugging and unlocking by remote control. With Conrad and various other workers there’s a lot to buy. But the things are then connected to the horn and that sounds really crappy. I’m looking for a sound like the US cars have. Is there such a thing to buy? I know, the topic doesn’t really fit into this forum, but actually it doesn’t fit anywhere *g* but somewhere I have to post it. ciao cyber ghost
