Audi MMI 3G Basic 2016 - Burning Maps on DVD

Hi Guys,

I have updated my firmware from K0206 to K0257 and then to K0260. Now I have problems with updating the maps. Since I dont use dvd that much I want to burn the maps DVD1_Western_Europe and DVD2_Eastern_Europe to a Dvd, so the DVD can be inside the DVD player instead of wasting my only 32GB SD-card on that.
But how do I do that? Can I burn MAP1 and MAP2 on seperate discs? If I do that, will I need to change between cds if I am in Eastern Europe and then switch it back again when I am in Western Europe? That would be so annoying.

I am using ImgBurn on PC.
I have bought "Verbatim 8x DVD+R Dual Layer 8,5GB", so I hopefully can burn both MAP1 and MAP2 on one DVD.
Both files are ISO

Thanks
