I have an old Sony Walkman that works on my computer but won't connect to a USB cable for my Kenwood car radio. I think it needs new firmware but it has never been updated since I got it. The intermediate firmware doesn't seem to be available any more so I haven't been able to update to 2.11 because I don't have 2.0. I've been to the Sony site and they just say update: a real Catch 22. Is there any place I can update this Walkman to make it playable?
Thanks for any help.
