Hello,
just received my Avic-n3 today and took it to bestbuy to be installed into a 2000 Buick Century. once the installer was finished and powered it on you can't turn up/down the volume, and it will always display "mute" in the bottom left corner.
when putting in a cd it appears to be playing but as soon as i touch the volume control it shows mute.
now the installer has no idea what to do, he told me the unit just might be bad, i just wanted another opinion. also i have not yet put in a navigation disc does this affect it? (didnt wanna open one if i have to return all of it
