Steering wheel audio control

I just installed after market Kenwood radio in 2006 BMW. I purchased from Crutchfield with all components to keep my steering wheel control intact.

The radio and Bluetooth work great the strange thing is when I first start the car I have steering wheel control for about 5-8 seconds then it is gone. No more hands free have to work it via the radio. Talked with Crutchfield a number of times sent new components the results are the same no hands free control after about 5-8 seconds. After the initial install it worked for about 3 days before it stopped? Any ideas??
