Hi Colin,
Thanks for the info,I have registered on the my lexus portal site without ID,
I have then gone to the car with my bluetooth enabled and 4g/ mobile data tethering enabled (I can browse sites),
last night when i tried as you suggested above, it didnt work, but this evening about 10 mins ago, tried again and hey presto its working :D
Thanks for the help Colin,
