Ok so I've seen tons of threads and read through all of them regarding the issues with the navigation ML systems in the LX470s. However, I have not found a single person talking about the issue I'm currently going through, and I'm hoping someone here can help me.
I bought my 2003 LX470 2ish years ago with a working sound system, albeit with speakers blown beyond repair. I replaced the front two speakers with a JBL set as recommended by Crutchfield so I could have some sound that was decent. I ran this setup since I have purchased the truck.
Three months ago I started to noticed static/crackling in the passenger door speaker - no biggie, it's probably starting to go out and needs replacement. Two months ago, I get in the truck and there's zero noise at all. Speakers don't work and the screen doesn't beep when I select anything. The navigation still works and the computer talking to me through the nav still works.
After a ton of digging and checking fuses, I assume it's the amplifier that has gone bad due to no bars appearing in the Audio menu that indicates volume level. I bite the bullet and order a refurbished amplifier that's of the exact serial number as mine. $450 later, I install the amp, fully anticipating to turn the truck on and enjoy my stereo again. No dice.
I proceed to check (again) every single fuse in the truck's engine bay and both footwells. I mean every one, not just the radio relevant ones. All fuses are 100% functional and there is no apparent issue. These checks were done both visually and with a continuity check via multimeter.
That bring me to today.
This video is currently my issue.
I have no idea what the problem is, and I'm about to embark on a 2 week trip through Ouray and Moab, so I'd love to have a stereo and not a bluetooth speaker. If anybody has any idea what this might be, I would really appreciate it. If I'm missing anything or forgetting something, let me know. I'm a pretty competent mechanical and electrical guy, which is partially why this is so frustrating. Thanks in advance!!
