I took my first road test yesterday of the Grenadier (I have taken them off-road for a short test prior). Very positive experience. One thing that got my attention was the small size of the rearview mirror and the VERY limited field of view. Between the barn doors, spare tire, and head rests it was the visual equivalent of breathing through a straw. My initial (incorrect) thought was to swap up out to a bigger mirror, but I think the manufacturer should make it a standard feature to the rearview mirror system you have.
Personally, I'm not a fan of all the electronic crap, the less the better when you are far from pavement. But in this case, a mirror that can also switch to a rear-view picture while you're driving is a practical redundant exception. I can turn my head to backup, but while driving 75 MPH...probably not the best idea.
I was told my Grenadier will arrive in December (we shall see), but when it does arrive, one of my initial upgrades will be to a system like yours.
Thanks for information!
