I have an Avic Z2 that has been upgraded to Z3 with larger drive. Also has all options as far as I know. BT, XM, iPod adapter, etc.
It recently started slipping trying to tilt the screen which I realize is the plastic gear and can be repaired by pinning or sending off for $90-$120.
I am just thinking about upgrading to something different instead of having it repaired. Is there a market for these things still? Works great (except tilt) and is installed in a garage queen with low usage so condition is excellent.
