Hi all,

 

Had my lovely new Superb for a couple of weeks now and I have read about maps updates via this forum.  Having visited http://updateportal.skoda-auto.com/en-GB and entered my VIN I find that ECE 2020/2021  (Valid since CW 25 2020) is available.  I guess the name format is week commencing 25 2020?

 

I've downloaded the maps several times (26GB each time!) on different devices and get no issues when downloading.

 

When I come to extract using 7.zip (as recommended) on wIndows 10 machines, I encounter several checksum errors with files inside the zip.

 

Has anyone else downloaded and extracted successfully?  I dont want to copy the 26GB to an SD card and then try to install in the Columbus if there are corrupt files....

 

Many thanks in advance

 

Paul

That's weird. I downloaded the same file a few days ago, no issues when downloading and no errors showing up while unzipping on Windows, only tried once as no need to repeat it.

Haven't launched the update yet as I plan to do it during a coming small trip but all seems good with the file.

I take it you are unzipping to the computer's hard drive, not on the SD directly?

Yes, very weird - just downloaded again this evening and no issues found?!

 

Unzipping directly to hard drive, then copy to new SD.

 

Will give the update a try tomorrow 🙂

try another unpacker, i used to WinRar and Total Commander

or download 7z from VW portal,

If the columbus has WiFi you could try connecting to your home network (if in range) and let it pull the relevant files directly. Much to my surprise this worked first time for me (although I just did the UK)

If you are using a Windows 10 computer then you don't need "7.zip" or any other external apps to extract files from a zipped file. Windows 10 has basic  zipfile extraction built-in and has done for years.

 

Simply RIGHT-click the zipped file, select "Extract All..." then choose the location where the extracted files will be placed.

 

For Windows 10 users this is the safest option, since some of the free downloads of "7.zip" or "WinRAR" can contain adware or other unwanted apps that can be installed on your computer.

Was about to say the same thing, no need for messing with external apps, I believe even Windows 7 had it?

Zip utility included in Windows might be suitable, yes. But I've had issues with unzipping files before both with Windows and Winzip. 7Zip has never once failed. Plus if you choose to download anything from Cnet and the like instead of 7Zips own site (which is free anyway so I don't understand the "Free Download" - "Adware" comment) then expect them to sideload all sorts of unwanted crap.

The Windows built-in "unzip" cannot handle zip files that have been password protected (which is not the case here). It also cannot handle other compressed file formats such as "RAR" which you occasionally encounter (again, not the case here). But I've always found it pretty solid and reliable with normal zip files and have certainly never had any problems unzipping Skoda/VW map updates using it.

 

As to the "adware" warning - many people locate software to download by using a Google search. It's not uncommon for those searches to take you to sites that are less reputable than Cnet and some of those sites are setup with multiple, deliberately confusing, "download here" links that will download software other than what you're actually looking for. I've had to remove "Mindspark", "MyWebSearch" and "DriverUpdate" so many times from people's PCs that I feel it's always worth warning people to be careful about what they download for free from the internet.

 

 

That's strange, because when I search with Google for 7zip, the first result is 7zips own site. I can't see me going past that to find a dodgy site / link. 😉

Upgraded via SD card work a treat - thanks for all the advice above.  No idea why there was issues with previous downloads - all sorted now though :-)
