I don't think I really know what I am doing, but I have loaded 9.465 and then overwritten TTsystem with the SE version, so assume this is the SE NC. This now gives me ALG and IQroutes again. If I switch between x30 and x40lite it now changes from old colours to new colours/icons.
The same change in 9.485 does nothing, it just stays with old colours/icons and no IQ or ALG.
I have now added rm and runclean to the 465 version and that increased the free RAM to 6MB. I think I shall stick here as that's about as good as I am going to get with me old unit now. The GPS module is still a bit fussy starting, it doesn't like starting after the 9.485 SD has been removed - I quess a flash data problem.
I did do a cleanflash though.
Thanks for all your help.
