I bought a avic z3 and when i first got it hooked up i tried to play a Dvd and it wouldnt play the radio said unreadable disc but it was a burned dvd so I went and bought a brand new dvd from the store that wasnt burned but it didnt work either so I bought me a seperate dvd player and got it hooked up to my aux plug and my headrest tv play just fine moving r not but the radio still wont let me c a image while moving what can do about this problem someone told me that there was a software that i could download but i cant find it.

You need to do the 2 wirebypass. See the sticky post in the Z Series Hacks forum.

that sucks the dvd reader didn't work!

mine doesn't either... i wonder if it's a common problem with Z units???

or could it be the z3 upgrade? i have to put my z1 hard drive back in and see if the dvd/cd's play or not.
