So i got a Pioneer U220 for my P330Bt, i tried to install it yesterday and i couldnt get it to work
I got my HU installed at a shop and i didnt feel like going through all the wires to solder the power connections and whatever. So i got an add a fuse put it in the radio fuse spot which is a 15, the power wire has its own fuse too. I wired the ground to the other side onto a bolt. Wired the connection to the back of the HU. Then i wired the GPS antenna to my dashboard for now, till i figure out how to get it to the roof.

But when i hold the rest button and go to mode on my HU nothing shows up, and theres no power light on the U220.

Any ideas? I wanna try wiring the positive to maybe a different fuse that has a 10? but i dont know which has constant power

 

u mean acc? the harness will have constant but no acc (red)
