Success !! I am finally able to connect. I went in to my Iphone Bluetooth settings and had it forget device ( Bike ) . I then started all over and entered the new pin number and everything is working now. Thanks again for the suggestions from all of you.
Thank you for this tip. I spent literally days searching various sources to find out why my iphone could connect to my wife's Vado 3.0 but not mine. Tried multiple methods and nothing worked until I read your post. Yesterday was the first time in weeks I was able to connect. Of course I wonder how long this will work, but at least for now I consider this solved.
