I just tried to install the oem oem night day oem into my 2005 X5.

I downloaded the file and burnt it on a cd-r at 1X using imgburn.

I followed the directions and after a few seconds I got the message saying my navigation would be updated, but I got an error that said the disk is invalid and the dvd drive had spat the disk out. Now my navigation system remains blank. I left the car on for a few minutes and tried powering off and on. Any thoughts what I did wrong or how to fix it?

Thanks, Robert
