Hello, I am wondering if there is something different needed when hooking up a 197 in vehicle. I have a rack with 3 scanners in it and that is hooked directly to battery. I have the unidens which work and show 12 v. I have the 197 which shows 13.8 v when I attempt to hook in 197 it will not power up. Is there any way to hook direct to make this work in vehicle or is some type of converter or adapter needed to get back to 12 volt? Thanks for any help.
