Likely will only use the gauges on long trips or when I think I am having issues. ThanksI've used that with an app called Torque for Android (there is also a Torque Lite which is free but I didn't find it to be too useful). I only use it to diagnose issues so I don't generally have it up and running though when I towed our travel trailer the first few times I did use it to check the transmission temperature. I have found that it connects very reliably to the Ranger in the handful of times that I've tried it.
