My navigation drive shows a navigation disc error. I pop out the disc and it has radial scratches coming from the drive itself. Hoping that it was the result of 7 years of use, I polish out the scratches and drop it back in. It works for 1 week and then same error, same condition. I find it hard to believe there is dust on the lens and that dust is scratching a relatively hard plastic disc. I suspect the lens itself is touching the disc and thus scratching it.

Anyone else experience this? Anyone repair it? The drive is easy to remove and take apart but I am not sure what the next steps are.

Last resort is pay $300 or so for the repair service.

Thanks!

I remember finding a description of cleaning the laser read head and/or laser. I don't remember if was on this site or WWW.

I had this problem and went to Alpine for rebuild ($180 at that time) and it's still working fine. They said some parts had to be replaced.

Won't hurt to open up and try to clean.

good luck
