I have a 2010 Genesis V8 Sedan. The keyboard control knob, part number 965443m020 appears to be stripped. The dealer quoted $333.00 for the knob which I found for far less online. To replace the console is $1,100.00 just for the part at the dealer. I would like to know how to remove the knob to see if it is stripped. I've seen a picture of the underside on an ebay offer and it seems to only have four notches. Has anyone attempted to replace this control knob yet? Very frustrated and don't want to get ripped off!
