Thanks Bumpkin

, the intercom unit is powered by the bike, and I had purchased a GPS lead that I thought fitted both ends as both jack plugs click in

. But with both jack plugs in there are no voice commands with the satnav jack plug just pull out half way then there is voice commands. So it looks like they've changed the jack plug size

But I will contact Chain speed or Autocom for the correct lead, and thanks again for the input

.
