Want a monitor only to monitor different things as I’m pulling trailers etc. I do not want a tuner. Edge has the CTS3 that is a monitor that just plugs into the OBD2 ports. Edge representatives told me that “officially” it does not support the 2021 Sierra 1500 AT4 6.2 gas yet. I mean, it’s only a monitor, not a tuner that is going to change anything, and can be used on “most” vehicles with an OBD2 port. I’m thinking of going ahead and purchasing, as when it does “officially” support the 2021 GMC Sierra- I can update via the Internet. What are y’all’s thoughts?
