Hi,
I notice you have listed Grandata.co.uk as a source for the spare parts. I actually found this site by chance myself earlier in the week and ordered the laser unit. But...I now realise I may have ordered the wrong part as it's frequently mentioned you need the laser pick-up with the black plastic cap, not the white which Grandata supply.
Description from website: Sanyo.SFHD4 DVD Laser white cap
So is the link posted in this thread incorrect, as it states it's a DVD laser pickup (not CD)??
If not, I will have to go to someone like Dalbani to source the parts.

Thans in advance.

Edit: I just re-read the whole thread and noticed M3Zenergy has fitted the same unit to his but reads DVD's only so I guess my question has been answered. Dont think I would need to use CD's in the Nav drive unless updating firmware??
