schematic for Alpine PXA-H510

[honfatboy]

Bought one of these on ebay...but the display has quit working. It seems to be a loose wire maybe in the DIN cable, but jiggling doesn't seem to fix it. I think it maybe broken clean.

Any ideas where I might find a schematic for the remote (RUA-4120)?

The remote schematic may be in the service manual for the PXA-H510. It is available from PAC Parts
