Sat Nav stopped working

[Bluethunder]

Hi Guys,

My Sat Nav has suddenly stopped working and displays the following on screen message "Unable to read data. Check if the map DVD is correct"

Tried pressing the menu button but nothing happens... So I called Lexus but was told that I need to pay a £90 "diagnostic fee" even though I have the extended warranty which I questioned but they were insistent that I would need to pay that.

Can anyone help?

 

Cheers,

Nean

Have you tried taking the DVD out and seeing if the disc is ok?

 

NB: take front off clock panel before pressing eject!!

Having had the nav screen out fitting the double din stereo, I would try disconnecting the Battery for a little while to see if that helps.

I removed the DVD, cleaned it and load it again but same error message.

So I then tried disconnecting the Battery for a few minutes then tried again but this time the message was that no program could be read and to consult the dealer.

Looks like need to head to the dealer! :(...
