I am trying to reinstall my CDX-L410X in an '05 Chevy Colorado. I had it installed in my '94 Grand Prix for about 5 years before removing it when I sold the car.

I bought a Scosche wiring harness adapter, and am getting power to the unit (it will take and eject CDs) but it won't turn on. I've tried the reset button and have checked that all of the connections are correct three times.

Suggestions? It was working fine when I took it out of the car.
