My AVIC-D3 has been working fine for a month or two. Lately though, when I start up my car, it sometimes will freeze on the start up Pioneer logo. The radio still functions and if I press the knob, it will switch sources(to iPod, etc.) but it won't come off of the Pioneer screen. Does anybody know what might be causing this?

Have you tried resetting it?

Does this happen with and without the NAV disk in?

I have reset it twice. I generally leave the nav disc in because I use my iPod for music. I'm pretty sure it is freezing while it's trying to load up the nav.

does it still freeze when you dont have any disc in it? I would try to make a backup of the disc and see it still freeze with backup disc.

Update:

The navi sometimes "reboots" itself randomly.

I've also had it give me blank maps sometimes for certain zooms of maps (for example: at 10mi view itll be blank, but at 20mi view it will show the map).

It probably isn't the iPod because it has frozen up without the iPod connected. I don't recall if I've tried it without the navi disc. Could a corrupt/damaged navi disc really cause the whole thing to freeze up and get stuck on that Pioneer screen?

Like I mentioned, the functions always work, such as pressing the arrows to go to next/previous song, volume, etc. It's just that the screen stays on the Pioneer logo.

I'm going to try burning a back-up of the navi disc(I backed it up on my computer when I purchased it just incase). I really hope that solves it because I don't want to have to pull it out and warranty it

You didn't buy this product on ebay did you? Might be a defective disc drive.

No, I purchased it from Crutchfield. I thought it might be the disc drive and I'm not sure how else I can test it, besides putting DVD's in there, like movies, and seeing if they freeze up as well.

I'm just hoping that it is just the navi DVD, because I really don't want to have to take the unit out and ship it to them.
