Hey, i just purchased a Pioneer DEH-7800MP and I know for a fact it worked when i bought it from my friend. I took out my stock hu and hooked up everything properly, turned my car on and nothing happened. There seems to be no power at all to the hu, so i re-checked everything again and again but still nothing works. Can anyone suggest a reason(s) why its not working?//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
