I have a mid power XTL 5000 Dash Mount radio I want to record audio off of. Reading the service manual, I can do it with Pin 21 + GND, but will HKN6187B do what I'm looking to do? I would like audio out at a set level, regardless of what the volume is set on the XTL. Will HKN6187B work even though I have a dash mount version?

Thanks,
Tucker.
