I was in the same boat, where it may work 1 out of 12 times, and that 1 time it DID work, it would likely stop working 15-30mins later giving me a map error message.

I pulled the whole head unit out of the vehicle (very simple, used my hands/fingers to pull the bezel off - no tools needed, just grab a corner, and slowly pull straight out, then work your way around).

Stripped the head unit down by slowly analyzing what needed to come apart - if I recall there was a ribbon cable which has small tabs on the side that need to be pulled up, then the ribbon slides out easily. Got down to the laser, cleaned it with some alcohol (or flat screen tv cleaner stuff - don't remember) using a q-tip. Put it all back together, been working perfectly for almost 2 years.

The only complicated part was analyzing the actual unit on my dining room table, and slowly figuring out what needed to come apart to open it up and get to the laser. If anyone has any tech savvy kids who have worked on computers, or game consoles, this should be a breeze to get through.
I applaud you... I currently have my radio out and cannot for the life of me see how it comes apart... I have the pair of DVD drives loose, but they won't come out of the unit. I'm just about to give up.

Well... I didn't give up and finally got it apart. I couldn't really get at the lens though. I did try with a q-tip and blasted it with some air. Went back together without too many problems and it still works. Now we wait and see if it stays working or not!

You guys are a bit more adventurous than me. I would hate to try it, mess things up so bad then just be totally without a working radio.

Great job Calab! I also recall it took me a while of poking and pulling at to figure out how to get it apart. I had to walk away from it a couple of times - but kept at it until I figured it out. If I remember, it opened up kinda like a book with the 2 halves coming apart which is how I accessed the laser.
