Wow, night and day difference! Breath new life into an old head unit. Again thank you!

Thank you! I'll give this a try.

I know this unit is old but it was free and I plan to use it for a while. Does anybody have any of the hybrid firmware files? I'm on 2.008000 right now, but I'd like to check out the hybrid firmware. Can't find any links that still work. Any help is appreciated! Thanks.

Cool, I'll try that before I throw this thing out the window. LOL!

Think the rca harness itself is bad?

Ok thought my D3 had bad pico fuse, not sure now. The rear rca's work fine but the front and sub rca's have really bad noise. I've tried grounding the front and sub rca's but that had no effect on the noise. I've tried brand new rca's, that didn't help. Tried a different head unit and all noise went away. I like my D3 but if I can't figure this out, its going to have to go! Any help is appreciated. P.S. I tried searching but couldn't find anything that was close to my problem.
