BUT: now I've obtained a part system with a widescreen head admittedly with a scratch on the screen, and a Mk4 drive albeit with a non functional DVD drive. Believe me they were still worth it at the price.
Questions: How do I properly identify a 16:9 tuner? I guess none of the Rover parts were ever widescreen. What's the right price for one?
Next, has anyone done a repair on the DVD? I've seen replacement lasers for less than Â£20, I'm told drives are about Â£80, and repair services for Â£150 or thereabouts. All vastly cheaper than buying a new full Mk4, which I'd not planned to do.
