I've had my Z1 installed for about a week now and I'm still not quite finished (VSS wire, reverse wire, and backup camera, as well as a permanently-wired phone charger). The only problem I've had to far is with DVD playback.

It'll start off fine but as it gets to a certain point on the disc, it'll get all jumpy and give an "unreadable disc" error. It's at a different point on each DVD but is consistent on each DVD as to where it will stop reading.

Audio playback is completely flawless and the DVDs are scratch-free, which leads me to believe that this is a laser problem. Should I try one of those cleaning systems or will that just add to the problem?

Thanks in advance,

I had exactly the same problem when I tried burning movies for mine. If you are burning these yourself it's probably your DVD burner. I purchased a new burner and my problems went away. You can also try burning your DVD's a a slower speed. Sometimes that helps.

Are you having this problem with commercial DVD's? If so your Z1 is probably bad.

It's happening with commercial DVDs... I got the unit as a demo and it had only been switched on for 2 weeks. Got a great price on it, too. I'm still within 30 days of buying it so I can take it back and since everyone's out of stock, I might get a Z2 as a replacement. After toiling over this install it just seems like a gigantic pain in the ass to get it replaced though.

We had the same problem with a Sony DVD player here at the house, but that was with burned discs. It did it with my Pulp Fiction DVD and my girlfriend's immaculate Family Guy DVD, so I know it's not an isolated incident. As a last-ditch attempt I might try a DVD lens cleaner and see what happens; I've got nothing to lose at this point.

Scratched DVD perhaps? Maybe your Avic is more sensitive to the scratches than your other DVD players.

...and the DVDs are scratch-free...

Oops! I didn't read your original post closely enough. Just ignore mine! But it still sounds like problems I've had with dirty or scratched DVDs.

sometimes vibration has a lot to do with it. If you havea lowered car, or one with very stiff suspension, you will get that error. Good thing the 3000Gt and corvette have adjustable suspension

My car is very low to the ground as stock and has a rather stiff ride. I did notice it get worse when I was up to speed. However, I have tried this with the car stopped. I specifically tried going through the scenes on the Family Guy DVD without the engine running and it still gave me problems. I'm picking up a lens cleaning kit tomorrow and trying my luck.

Those are a bad idea. most of the time they throw the laser lens further out of wack, at least in automotive applicaations.
