Hi, I have just installed this, and looking to connect with the app. I've tried the default bluetooth code "000000" which it doesnt like. I've also tried resetting the pin, which it says it needs a PUK for. Apparently this can be found on a label on the side of the device, also where the pin code is. Unless i'm very thick, or lacking eyesight - i have no label with either, anywhere on my device, box or manual. Any suggestions as to what to do please? Thanks.
