I'm thinking of upgrading my N1 to a Z since the ribbon cable failed and i'm a bit tired of fixing stuff with it.

Some of the rear plugs look the same from the pics i saw, which means nothing, so does anyone have info on whether or not its pin compatible, same, mostly or not at all ?

No, you will have to switch harnesses and plugs. Should take you about three minutes

Thanks CT, i ended up just repairing the flex cable on my N1, since i already had it apart it actually took less than 5 minutes since the flex cable had just partially split.

N1!!!! Man get a new unit already.

I almost did, but played around with some of the newer double DIN's and didn't see anything that really made me want to jump over. Plus i haven't finished hacking the rom of the n1, i'm determined to remove that warning in code one day. then i'll buy a new unit ! :0
