Hi all. My 2005 E320CDI has COMAND with V5.1 in the boot. I have no access to the nav menus via the head unit. I don't have ETA on the display but I do have TMC.
If I were to purchase the V8 disc, what should I expect? I know the sellers on Ebay usually state that they will also provide a firmware upgrade disc as part of the deal, but is this necessary in my case (if I choose to go down this route)?
Would I get ETA displayed with only the mapping disc updated, or is this part of the separate firmware upgrade?
I'm thoroughly confused.
As an aside, what are the chances of getting the service dept to facilitate multi-region playback on the DVD player, being as how I can't get in there myself?
Cheers,
Corned
