Peter,

You can pick one up from ebay or maybe ask a UK beoworld person to send one over. Panasonic in Australia don't know which units use the same codes, Topfield do but its a different requirement.

Lintronic support the Panasonic range, so does the Pronto and a few other high end remote systems as another avenue. It maybe another avenue to check...

Still waiting for that Pizza night... 

cheers, beoaus..
