hi guys
i could do with a little info or help on a problem i have with my 2000 gs 300 sport sat nav
when i bought the car the touch screen had a check cd rom message on it when starting the car , and after 30 secs or so the screen changed to the usuall audio and air con functions, but no sat nav worked
i wanted to check the disc was ok so ejected it out of its holder, when i re inserted it all the fuctions on the screen, ie audio and air con have now disapeard and im left with just a black screen with the words check cd rom
iv taken the car to a lexus dealer and they say it must be the cd rom driver faulty.
iv now sent this away to be hopefully fixed
what i would like to know is
dose the cd disc also supply the on screen data for the air con and audio and the sat nav info
lexus tell me they have never seen the screen go blank , just by removeing the disc
is this true or faulse?
if the cd is nothing to do with the air con and audio touch functions , is there anything i need to check or do to get it back on the screen
at night time the screen has a glow to it , so theres power there but nothing from the on/off audio button and no sound at all from the system
any info would be helpfull
