NGT1 Nav Disk Upgrade

[JohnEclass]

Hi All,

Got a 2014 DVD Europe to update my 2009 W211 Comand, dealership tech guy said it might take up to 1/2 hour, might error, might just refuse as its upgrading from too far back.

Well I followed instructions.....key in ignition setting 2, switch Nav on, then remove old DVD and insert new.....all good, 2 bars across screen stating updating. Lasted about 2 mins then unit switched off......left it 5 mins nothing so switched unit back on and it started as normal......switched ignition off, locked car left it 5 mins then back in ignition on, all started as normal and worked perfectly well, guided me to Rugby today no problem.

So question is has it really fully updated in 2 mins?.....does it retain old maps in memory.....should I just stop worrying about it??

Cheers

Did you actually get an NTG1 COMAND DVD? If your car build date is 07/2008 or later, you should have NTG 2.5 where it would take much longer to download all maps data.

Shame its not the Cd as I really want one of those but they seem alot of money to update an outdated system.

Apparently it's a 2008 build car on a 2009 registration. Bought DVD from comand on line uk they checked vin and said definitely NGT1 :-(

As its NTG1, 2 minutes is about right. It loads the navigation processor firmware from the disk. It then access the disk for mapping - almost nothing is stored in memory when not navigating

Ok Thanks, the Mercedes Tech threw me with his could take 30mins..... Would have thought he should have known it was NGT1!
Will stop worrying and carry on enjoying the car .
