How much effort is this? Couldn't find a DIY.

Basically, my navigation won't read the disk anymore and I'm looking at replacing it with a used one.

Thanks.

Thanks all!

Dang that's more work than I had hoped for though. Nothing I can't do, just more than I had hoped.

Any tips on fixing the "unable to read dvd" error code prior to replacing? I've got a cleaner disc, but not sure it actually gets to the cleaning brushes part of the cd when I play the disc. Also read that it's probably not dirt, but the laser motor itself.

Anyways, any suggestions before I replace hardware? Was working before I shipped the car back to the states, but it did have a few cases here and there where it acted up prior so it was probably on its way out.
