Trailer Technology Group (AVS) gives you the Trailer Reverse Steering Control (XA1, the “knob”), and the DRVM 3.0 (GNQ) with the additional side camera views. AVF gives you the old DRVM (GRG) without the side camera views (best I can tell).
The old DRVM (GRG) is also included in the Limited Level 1 package (A69).
Assuming the order guide is correct (that may be a big assumption) I can’t find a way to get the DRVM 3.0 without the knob, which as mentioned above prevents you from getting aux switches.
I’m not sure we’ll be able to be certain what mirror comes with which package combinations until trucks start showing up.raider reverse steering control
