Here's the scenario.............

Removed the stock headunit and Nav system. Replaced with a Kenwood BT645 headunit and a Garmin GVN53 Nav system. Here's the issue I'm having........The factory nav screen will not power up unless the factory radio stays plugged in. Once I unplug it, screen goes dead, and will not power back on. Also, I seen h20boy's install, and noticed he still had the Jag clock, etc on his factory nav screen. Any insight from anyone??

Thanks in advance!
