I am proably changing gers and am going to install an aftermarket stereo in my 06. i take it I can just hook the new head unit in place of the old one with the use of a adapter harness? is there anything else I need to know? I ask because i own a C4 and in it you had to also hook up two resistors in order to not have an error message.
I have a pioneer in my c6. I don't think there are any resistors. A lot of wiring was involved along with the harness. I recommend speaking to Dennis at D D mods here on the forum. He can hook you up with almost any unit and send it Pre wired so it will be Plug and play!
that is not an issue, I was just worried as with the C4, I ordered the stereo from Crutchfield along with the wiring harness and when it was installed I all of a sudden had a sys message, and it turned out that some of the C4 models you had to install two resistors in line to not have this.
