Sat Nav Laser Replacement
« on: 09 November 2014, 20:45:53 »

Demo unit is an NCDR1500, but procedure is identical for NCDC2013, NCDC2015, NCDR1100 and NCDR1500, with the exception of front panel removal is slightly different on NCDC units.

Tools required are a selection of small torx bits, long reach Phillips size 0 and miniature nose pliers.

Estimated time take for somebody reasonably comfortable with these sort of stripdowns, 2-3hrs.

Symptoms of a failing laser are random CD ejects, and errors about unable to read CD.

Before removing the headunit from the car, eject any CDs!!

This is the pesky part:


Remove the 2 screws holding the top to the amps heatsink:


Prise up the rear corners of the top, and remove the top:


(On NCDR only) Turn the unit over, prise up the corners and remove the base:


(NCDC units, remove CDC unit, see CDC3 swap guide)

Remove the front panel. Be careful, the small clips are incredibly brittle! NCDC units are slightly different, but still have 2 of these clips at top, 2 at bottom, but with an additional clip on each side as well.




Undo the 4 screws holding the CD unit in place:






Rest the CD unit towards the back, do not strain the ribbons:


Where the ribbons meet the connectors on the main board:


Move back the rear part of connector:


This then allows you to unplug the ribbons, and lift the CD unit clear.

Remove the top board. Its held in with several clips which can get brittle, so proceed with caution:


The ribbon is double sided taped to the casing, gently peel ribbon away from case. Then remove the 4 screws


Pop the top off.

Remove 3 screws pictured (note for this picture, extra parts have already been removed for clarity):


Unplug laser, by pushing the white tabs back a bit:


Unplug motor by simply pulling ribbon out (best to grab by white tabs on the ribbon:


Remove the 2 screws (arrowed red) at the back of the unit, and remove the mounting bracket (arrowed blue):


Remove the 2 springs at the rear of the mechanism:



The key to removing the mechanism from the frame is this white moulding. Pull it towards the front of the unit - this unlatches the entire right side:


Pull the mech out from the left of the casing.

Turn the mech upside down, and remove screw:


Lift off metal plate.

Pushing to the right slightly, pop out the worm gear:


Pop in new laser.


Rebuild is the opposite. Bit fiddly to get the left side of mechanism to fit in the cage, esp at the back. Pull the white moulding on right backwards to lock mechanism in place.

Remember, just before refitting CD unit to HU, you need to cut out the bridge:

If the white moulding on the right drops out or becomes dislodged, this is how its fitted:
