I have 2 auto dimming compass mirrors for RX300's.
One of them has had the cable cut, but I have tested it, and the regular non-compass mirror cable will work, so you can swap yours out (I bought it for a potential radar detector project, but am selling the car)
The other one is ready to go, and is plug and play.
Both are IVORY
Cut-cord mirror is $25 shipped to lower 48 states
Full-cord mirror is SOLD
