Question on Genuine Map Update Disk

[SkyJawa]

Hi all

Just wondered if someone could confirm that a genuine disk on the rear still looks like a DVD-R, or does it look like a proper DVD movie disk that's silver?

Reason being I can't get my RNS to update the maps, and I'm now trying what I believe is a genuine disk.........

I've tried 3 disks from 3 different writers and always get DVD/CD Error including on the genuine? disk I'm now trying.  However, using a single layer DVD for firmware updates it works fine 

Its looking like a new DVD drive perhaps?  

Thanks
Neil
