Hello all.
I'm pretty much a novice when it comes to vehicle mechanics and was hoping somebody has some advice for me:
I have a 2005 TSX AT w Navi and turned on my car earlier today to find that the display above the center console in the dash wasn't working. I then tried to power on the radio only to find that none of those buttons work either. No audio, can't eject my CDs, nada.

All of the AC and navigation controls work perfectly, it's just the audio and that display.
I was trying to find out if we the problem is a blown fuse.. the only one I found relevant to my issues is the #6 fuse in the interior fuse box (which pertains to the AMP), but it appears to be just fine.

Is there another fuse that I should be looking for?
Also, what else could the problem be?

Thanks in advance

 

I don't have nav in my 05, but from what I can remember reading here, the news is not good. I think it may be the unit. I'll let others confirm that, but I'm pretty sure it's not just a fuse.

 

I not 100% sure but isn't the radio/cd player a separate unit than the nav. from reading the op post the nav. seems to be working.

 

The nav and a/c are working, but don't they all share the same screen? (which doesn't seem to be)

 

Only fuse reference to the unit you are saying doesn't work also protects the NAVI, which is working. It ain't a fuse issue, and assuming you cannot get the audio to work using the NAVI display you have the following possibilities:

1) Radio was powered down and is asking for a code, but the backlight has failed so you cannot see it. If your playing around entered a false code three times, it's dealer to fix.

2) Component failure. Either replaceable units or the main unit is dying...bad news either way and you need the Honda computer to diagnose.

 

Thank you all for your help, I really appreciate it. I was upset when I heard that the problem might be with the unit.

However, I think I know what the problem might be: When coming home from work, I turned on my car to a song that I didn't like on the radio and switched to CD. After about 5 minutes of listening, it hit me that the AUDIO AND DASH DISPLAY WERE WORKING!

This means that the wiring is loose, right?!

 

I doubt it's loose wiring (it's not the 60's; the modular units used now to connect wires are pretty rugged). Sounds like #2 above, but no matter what, unless you're not going to fix it, you're going to have to visit the dealer. Guess work is just that: guess work and not particularly productive when something is broken (unless you don't plan on fixing it and then it doesn't matter anyway).
