Hey there, I have a quick question. I'm wondering if the rear view mirror in the newer Dodge Rams are a stand alone unit? Can I just glue it to an sweptline windshield and have the compass, temp (I realize there will be a sensor for this) as well as the auto dim features? Or is the compass run from the ECM. Any help would be greatly apprcaited.
Thanks,
Foddie.
