Hello Everyone,
I need some help before I contact MB, so that I know I am asking the right thing
I have recently purchased an 2010 ML350 and a family member already has a 2006 ML320.
I think the map updates are about £150 from MB, but I cannot find the command model on one of them if any one can help?
Both are W164 type from what I can find.
This is my car (ML350) and I can found out it is the NTG2.5 type command center with SD slot and hard drive:
Mercedes-Benz M-Class 2010 W164 [2005-2011] SUV SUV ML 350 CDi 4matic 2987ccm 224HP 165KW (Diesel) NTG2.5
My family member has(ML320):
Mercedes-Benz M-Class 2006 W164 [2005-2016] SUV SUV ML 320 CDi 4matic 2987ccm 224HP 165KW (Diesel).
For the ML320 I think I just need to buy the DVD from MB dealership, but does anyone know the NTG version on that model? It is NTG1.0? Also the maps have never been updated - can I buy the 2017 DVD or have I have to do an interim update first?
For the ML350, I have no idea what i need to get for the maps - do they sell a SD card version or do MB upload it to the car when you take it in?
Thank you!
