I will dig up this old thread because I just purchased my car. My phone (Verizon Droid Turbo) wouldn't connect either. It keeps saying Scanning or something like that. Then it fails after about 30 seconds.
I found it strange that any manufacturer would be using either of the default BT codes. Most systems provide a random number to input, but I will chalk this up to mine being a preowned (read used) 2013 model year.
I assume you are saying to change the code on the car system? If so, I will read up on how to do that with this interface.
