Hey guys,
Recently bought new JVC head unit for my 2003 SE non bose. I have every wire soldered and connected correctly, grounded the radio wire to the chassis, and have checked every fuse. Cannot get the unit to turn on and am running out of ideas. Any help would be greatly appreciated! Thanks!

 

Something is probably not connected correctly. Triple check all of your connections. Get a multi-meter and make sure you are getting voltage. Also check where you connected the ground to make sure it's good. Did you connect both the switched power and the constant?

 

Went back and reconnected everything, both powers are soldered to the corresponding wire. Out of ideas. Multi-meter read nothing so my next option is fuse? none are blow though..

 

Where did u get the Unit from? It mite have a Lock out Code on it. & may have u locked out. If so u will have 2 take it 2 a audio store & have it unlocked

 

Bought it from Best Buy, maybe there's a fuse I'm missing?

 

If theirs no power at the radio harness I would check your fuses. Also check the fuses on the driver side under the hood. I know when I was wiring leds, I blew a fuse by accident and it cut off my radio and my cluster lights.

 

Fuse #1 in the top left corner of the fuse panel is for the radio power. Pull it out and check it with a meter or swap it. Sometime a fuse will look good to the eye.

In the nissan wire harness, check for voltage onthe purple wire in the connector that holds 12 wires. It is one of the corner wires, this is from the fuse. Don't forget to have the key in the ACC or ON position.

 

is the antenna wire plugged in, too?

 

I know for the Bose system in the 4th gen there are audio fuses in the engine bay as well as in the cabin. You may have them too. Check those.

 

Check the Antenna plug. If thats not in then the unit wont work.
