i managed to get a more upto date sat nav cd for my mk 4 LS400 (cd ver 3.4). It came out of another mk 4 ls400 and was tested before i got it
When i put it in my satnav drive, the lexus logo appears.... after a few seconds the screen goes blank.... then a few seconds later the logo reapears. I left it for over 10 minutes, and nothing else happens
If i put the original CD back in (ver 2.1) everything works as normal.... sat nav is available almost immediatly
I have cleaned the new disc, it looks spotless, but this has made no difference
im thinking of getting a cd lens cleaner as a last resort, although as my original cd is working, im guessing it wont make much difference
anybody got any ideas?
