Hi, pretty new to all this but managed to download and install the 29.1 firmware upgrade without to many problems. I've got 2007.2 nav disc on my pc as an iso but not sure how i burn it to a disc. Do i just burn it straight to a disc as an iso or should i unwrap it to a folder first and then copy these files to disc. This might seem a stupid question but just not 100% sure on how to do this. Thanks for any help anyone might have and yes i've used the 'search' but couldn't find anything.
