Hi Mcleish
Have just joined the owners club as I am now the proud owner of a RX 300, as of the back end of December. Its a 5 4 plate. I would like to update my navigation system , to the 2010/11 system. Through your searching for the 2012/13 update. Would E-Bay be any good for me to look on, for the disk to upgrade to The 10/11.Sorry this does not help you any but would be O K for me
thanks very much
