Hi guys,

I added a powered sub and Sirius radio to my 2017 Fit EX today. After running all of the wires, I turned on the system and everything worked fine.

But when I went to push the head unit back into the dash, I lost power. Everywhere. I've checked all of the fuses I could think of and they all look good.

When I press the ignition button, I hear a relay click in the steering column and the push button lights up and the light flashes green. But that's it, nothing else.

Any ideas?

 

Hmmm. Assuming that you have your key fob in the card... Take the fob, and use it to press the start button.
Anything different happen?

 

fizzy99,

We have progress!! Using the fob I was able to start the car. I don't have radio power, and the interior lights don't activate with the door open, so I assume I must have blown a fuse. Any ideas which one?

Edit: It was the 'backup main' fuse under the hood. Swapped it out and now we're good to go. Thanks fizzy99!!

 

Awesome! Glad my suggestion lead to the fix.

 

My car did this to me when I was installing a stereo. I took the ground terminal off of the battery for a little bit and then reconnected it and everything seemed to work fine after that and I didn't run into anymore trouble.

Have a good day!
