Hi!
Hopefully someone with alarm know-how can answer your query. I have a V6 SE, but the alarm on mine was added later, doesn't work, and I haven't got into sorting that out yet!
Meanwhile we do have a Whatsapp Group for V6 owners, if you use Whatsapp and that's of interest to you. At the moment we have about a dozen members, which nowadays must account for at least a third of the V6s left on the road, and some members have more than one!
If so, leave a message below and I'll PM you a link to the group.
