Repairing Navigation DVD Drive Laser Head

If you ever get the dreaded MAP CD NOT FOUND or it takes a very long time to initialize, its highly likely that the DVD laser head is gone on the unit and needs replacing. After replacing the laser head my DVD Nav unit it just takes seconds to fire up and read the DVDs no problems I got to a point were I was carrying a tomtom in the glove box, when the Nav would just stop or wouldn't initialize again.

I looked on ebay and the prices for second hand units and they were extremely high and also considering you wouldn't know the state of the DVD laser head if it was going on it way out. So I opted in repairing it my self.

I attempted this repair today as my replacement laser had arrived from Germany. Took about 2 weeks to arrive. You can either buy the whole unit http://www.navigatie-onderdelen.nl/e...roducts/PH2038 which would be a straight forward install. I recommend this for people who are too sure about there soldering skills.

or just the DVD laser head for 23 euros if you handy with the soldering iron. http://www.navigatie-onderdelen.nl/e...roducts/PH2050


Tools required, pcb board type soldering iron, desoldering braid or desolder pump, Torx T4 to T8 screwdrivers and some watch precision screwdriver set.

Step 1 take the DVD unit out of the car, I didn't disconnect the battery at the time as the unit was in sleep mode.

Step 2 Slide the black mounting bracket.

Step 3 Lift the top of the DVD unit to expose the drive.

Step 4 Remove four torx screws holding the drive in.

Step 5 Do not remove the cable that is attached to the cable otherwise you will damage the ribbon and connector, it is too brittle and will break. instead remove the cable from the other end by lifting the board to the right up.

Step 6 Remove all other connectors as in the picture, so the drive is bare with just the ribbon.

Step 7 Desolder the shield from all four corners before lifting up to expose the DVD laser ribbon. I originally used the desolder pump it was no good, instead use the desolder braid instead much better. The desoldering pump was good as **** on a fish.

Step 8 Once heat shield is off, remove the DVD laser ribbon.

Step 9 Remove two screws on the opposite side that shield the laser from the top. Ensure you make a mental note or picture of the shield to how it is located, you will need a torx and a very small Philips head. The laser shield actuates a switch on the bottom and on the right is seated on a spindle.

Step 10 remove another two torx screws at the top of the two guide bars for the laser head.

Step 11 Gently prise the bars up and slide the laser DVD head out.

Step 12 On the new DVD laser head ribbon there will be two solder bridge points, you must remove these before the laser is operational ! use desolder braid and heat the top with the solder iron gently and is should come right off.

Step 13 Installing the laser is just reversing the process, ensure the DVD laser doesn't touch anything when you slide it on the bars. Use tweezers for this to lift the bars up it helps.

Step 14 Install back to car and enjoy the NAV again with super fast access to the maps

I'm having some issues with my cd nav player. Any tips to pin point which part is bad? Also the desolding pump that you are using is to small. I use a bigger one and gets the job done every time.

sure you can get a replacement laser for the CD unit in the US for about 20 bucks. The procedure would be the same just the laser head be different.
