hello all,
Bit of a noob to the lexus scene. I have a 51 plate is200 sport , alls great apart from my sat nav not working. there is an after market head unit installed , Its a horrible looking thing and looked like it was put in with boxing gloves to be honest.
When I open up the sat nav screen it reads "unable to read disc, please ensure correct disc installed" or something of the sort. When I got the car, the previous owner said, "Dont know why it doesn't work but in any case there is a sat nav disc in the glovebox" - its a copied disc. So after getting the car home, i went to the unit in the boot, pressed eject just in case and out popped a genuine lexus sat nav dvd. So i popped in the other disc just to see and a different error came up on the screen something along the lines of "incorrect disc inserted"
I can gather that the unit is reading the discs but still not booting up the sat nav system . I called lexus bristol and a nice chap in services said he was 90% sure it`s down to having an aftermarket head unit installed.
Has anyone else come across this error? Does anyone have a genuine working head unit lying around I could purchase?
Thanks in advance
Dave
