Nor could I. I did a ton of research on it and talking to the Techs at ARB before I bought and installed mine. I went that route because it controls everything in the Jeep from one panel. My compressor, lockers, frig, lights, comms, TMPS, and batteries. The installation is time consuming, it’s a lot more involved than the switch pros or the shitpod. But it will also automatically controls back up lights in reverse, front off road lights when your brights go on and a lot of other customized controls than that.
With the compressor accessory, you can inflate or deflate your tires to an exact psi and it always displays your current system pressure when the compressor is on. When you are filling them back up, It is a bit slow as the pressure gets close to the desire level because it adds air, then stops for a couple seconds to sample it, then adds more. I’ve had better luck setting the pressure about 5 psi high and then watching it and shutting it off when it gets to the desired pressure. I’ve set my Jeep up with a 4 tire fill up system, so it does all 4 at the same time.
The TMPS module shows current pressure of all 4 tires and your spare. There are two preset settings, on and off-road. Once you drop your tire pressure down, you can still monitor pressure at off-road level and if you get a leak in a tire, the alarm will sound.
Mines been installed and operating for a few months now and it hasn’t failed or locked up. It takes a bit to get used to the scrolling thru the menus, but once you set it up and get familiar with it, it’s smooth to operate it. Mounting the display has been the only issue so far. I liked it up high when my hardtop was on, but it was blinding when the sun would hit it with the top off.

So I relocated it down and it’s been a lot better by the center console
