Connection Problems

[finatic]

I installed the Bluestar2 unit in my 2005 Corvette and paired the unit. That worked fine. My problem is that every time I enter the car my phone will not auto connect to the Bluestar. I go into the settings on my phone and it shows it is paired with my Motorola Droid Maxx but does not connect until I select it then it connects right away. I tried pressing the multi function button (blue button) on my OnStar unit and the red light blinks but wont auto connect. This happens every time. Once again my equipment is

2005 Corvette with OnStar
Motorola Droid Maxx
Bluestar 2 unit

Any help would be appreciated I like the unit and don't want to return it.
