Guys i hate to burst the bubble but you should only be using genuine disks and not copies.
The reason has been talked on here time and time again.A copied disk will burn your DVD out twice as quick and be a very expensive repair.
Guess us 'Newbies' typed in Sat nav disc and came up with this single thread (well I did anyway) Got a quote from Honda in Croydon for a 2010 disc.... £170 inc VAT!!
