I was originally having some issues with my MKIV computer reading my burned Nav disks. It would only happen sometimes, most when you stop the car for a quick run to the store and come back out and start it up the DVD would have read issues.

On the recomendation of this site, I purchased a CD/DVD laser cleaner, but I am not sure how to make it work. The instructions indicate that you insert the DVD into the drive and select track 2 for cleaning. Unfortunately, I am not sure how to select track 2 on the MKIV computer. In an attempt to make it work, I woukld just insert it and eject it like 5 times, so that it could get that initial read\cleaning. It did not seem to resolve the issue though.

I just reburned a new copy since the one I am using is like a year or so old.

Any help would be appreciated.
