I live in a sparsely populated mountainous area, so the GPS functions of the 9500 were of little to no use to me. The Redline offers the best off-axis detection (around curves, over hills, etc), which was crucial for the mountain roads I drive most often.
I'm adding a Blendmount very soon, and I'll actually probably not leave the detector in the truck most of the time (short drive to work that I don't speed on - too curvy). I'll just pop it back on if I'm going anywhere further.

On the 9500 CI no need to tie it in too a switched location... You have the ability to mute with the press of the button on the remote... I have one and it works flawlessly. Nosbusa also runs one and is a delaer for them, they really are fantastic..
I think the reason for wiring to an upfitter was not to mute it, but to stop the laser jammer operation, after you slow the truck down.
I skipped jammers here - our cops can't afford lidar, and there are few places they can get out of the car & get a straight line of sight to get you.
Definitely talk to Busa when you buy one. My Redline came from him.
