Hello guys, I have a pioneer radio in my sc430 and I just added subs. Everything was working great, but since I still had my radio out I decided to take out the nav screen to replace it with a DIY idea I had. Now my radio won’t turn on and not off the climate function are working... I check the wires going into the radio no power at all!!! I’m like freaking out and I don’t know what else to do I plugged back in the Nav and still the radio won’t turn on nor do the climate controls work.. I even unplugged the battery.. HELP?!

Sorry about the typo... climate control and radio are not working

Have you check the fuse blocks? There are more than one associated with those components. Your owners manual for which ones and where the fuses are located.

looks like driver & passenger side boxes and engine compartment box too have fuses associated with both systems.

I haven’t check the fuses, but it literally was working I took out the nav screen and the two connectors that plug in and then everything stop working I noticed because the remote door stop working when I put everything back together and then boom radio not working either... was working right before that...

Check the fuses. Simple and quick.
