@Ritchi, i know this comes a little late but yes, they do work. You just dont have all the graphic items on your screen like rivers and lakes. But at least it shows the roads correctly and it does guide you to your destination, it has always worked for me. Be sure to burn it at slow speeds! the slower, the more likely your nav system will be to read the DVDs successfully.
Just tried it in my Lexus GS300 2003 and the DVD loaded fast and without any problem.
Navigation displays the map fine and it will find the destination I want but when its about to calculate route i get message "Route could not be found"
Can anyone tell me what is wrong.?
I've used verbatim DVD+R DL, liteon drive and imgburn with bookind type set to dvd-rom.
