Hey guys I am new hear. Sorry I have to start of by sharing my problem. I have a lexus IS250 2007 model. the screen on the navi unit is displaying a message saying " cannot read programme. Kindly consult the dealer." now the problem is that my Unit uses a software installed in a hard disk drive. so I am not able to change anything. I cannot access any function on the unit. Any one with Ideas on how i can fix this problem?

Your IS should be DVD based, I think it was 2010 before they moved to a flash memory device.

I would check that the DVD is installed, it's hidden behind the clock display 

Here's a you tube video showing how it's done

My Lexus IS300 F Sport 2007 has Dvd Based Navigation. Its showing " The Program cannot be read, Please Consult a Dealer". I have tried taking out the navigation Dvd (which looks good) but nothing changes. Have also tried disconnecting the Battery for 2 mins, turning the headlights on and then reconnecting the Battery. Is there any solution for this?

There is no 2007 IS300 F Sport. Please confirm what model you have.

Maybe its non F version. The only badges on it are the F sports on the side and rear. It has 3.5L V6 under the hood and the model year is 2007. Anyhow, i don't think there is a difference of navigation system between the F and normal version. I am still attaching a photo of how the navigation system looks like. I have ejected and reinserted the Navigation Dvd but there seems to be no change on the screen. Have also tried disconnecting the Battery for 10-15mins and still no change.
