Might be, and probably is a silly question......
You have got voice comands enabled? You can turn it on and off in the app.
Even sillier question.......
You are starting with "Hey Cardo" before the voive comand?
Haha yes and I've got the language set to English
If I'm sat in the front room looking like a right tosser with my helmet on, it works
as soon as I'm on the bike in traffic or going 30mph+ it doesn't work
my mate bought the same cardo and his is the same, different bike and helmet.
It was only a problem at first as i didn't know the equivalent button combo to do the things i wanted and relied on voice commands.
i know the buttons now and its quick and easy and works well.
all thats said i still think its a great comms unit.
Another thing (quirk lol)
It went through a stage where it would randomly start playing Spotify off my phone... i wouldn't mind if it played AC/DC or something but no... it plays taylor swift or the weekend shit
it did this for about a month and changed loads of settings, it only stopped when i deleted the Spotify app off my phone
so high wind noise = "Hey Cardo, plays some cheesy shit pop song"
When i say "Hey Cardo, play music" it now plays the songs directly off my phone which is great.
plus if I'm in an area with weak or no signal my music isn't interrupted
