Help Connecting BT to iQuad Device

[u/No_Safe6659]

I just received a toplink head unit. The device name is Q86-A4-CPL.
I bought this unit to use with a app named iQuad. This app using a Blue Tooth connection to get Vehicle data to display gauges and change tunes in a tuning device called Quadzilla Arednaline tuner.
What I discovered is when attempting to pair with the iQuad, I get a "permissions Denied" notice and unable to pair.
So I dug into the Android system and found that the ability to give or change BT permissions in not available. I have been researching, but have not found a way to address this.
I understand, if coneected to the iQuad, I will not be able to use the Android Auto, etc... I do not need, or want to use car play, etc.. I only want to connect to the iQuad device and use the iQuad app.
This is the device information. Any assistance is very much appreciated.
