Kenwood GRC-NV600 GRC-NV501 remote

Hi,

This isn't a high end system at all, but a good one that fits my need for my particular usage. The complete system is Kenwood GRC-NV600, its remote's model number is GRC-NV501. My remote's LCD screen is broken, so I am looking for a replacement. 

Anyone has GRC NV-600 you want to get rid of? Or just has the remote? Or know where I can get one? I searched everywhere, couldn't find an available one.

Thanks!
