FixedFirst step: buy a Valentine One...
:wave:
I hardwired my 9500ix in my 05 limited, it was very easy. the hardest/most time consuming is hiding the wiring for a clean look. I tapped into the cigarette lighter (+) wire and grounded it to a random bolt near the shifter.
I ran the wire under the driver's side panel and up the A-pillar, stuffed it into the headliner and out by the rearview mirror.
I also purchased the blendmount metal adapter to attach it to the mirror. expensive, but very clean look and it's sturdy.
Mine is a blendmount too.
