Lexus sat nav disc update

Hi,
I'm looking for the latest Lexus E16 West Europe sat nav disc update. Does anyone out there have one for sale or maybe a copy or a link to download it. It''s nearly £150 from a Lexus dealer and I'm hoping to obtain it for a lot less. PM me if thats ok.
Thanks in advance.

just had a scoot round a few satnav sites .. not much found

you might want to try usenet or torrent sites
