RenoTL

I have a 2010 TL SHAWD w/Tech and have set it up with 2 phones paired up - mine and my wife's. When we both get into the car, the HFL links up to my wife's phone, regardless of who is driving. I can switch the system to a different phone (mine) but I would like the car to pair up to my phone when both phones are in the car. When I go to the "Delete Phone" option, it lists both of our phones with hers in position #1. I have tried deleting her phone and re-adding it but it still ends up in position #1. I assume that I need the system to see my phone in position #1. Any ideas how I can make my phone the 1st choice for the HFL to pair to?
