I installed a polar fis + advanced box to my car today 
First of all when I tried to change the peramiters it hung on this screen 

And didn't do anything after that 
I was able to get the preset peramiters on screen 1 

And set the Bluetooth menu 
I tried dissconectIng everything and reconnecting to see if that worked 
But I now have an airbag warning light and I can't access any of the standard menus that I had before on the mfd 
Anyone had this issues or know how to fix them?
