I downloaded the HIGH12_P177_EU_201920.zip  (about 25.3 Gb) and the extraction to the 3 files MiB1, Mib1, and metainfo2.txt took about 35 mins.  Is this what others found?

I started to copy the files onto my 32Gb Sandisc Extreme SD Card (used for my HD Video Camera) and it said over 1 hour for the MiB2 folder and about 2hr 55mins for the MiB1 folder. 

This was not what I expected. The file data transfer rate was about 1.8 - 3 mb/sec. MUCH TOO SLOW. I cancelled the transfer and went back and reformated the SD card. I noticed that the "Allocations Unit Size" was set to 32Kilobytes. This was because  the SD card had been formatted by the HD Video Camera and was optimum for real time video transfer .

I changed it to "Default Allocation Size" . MiB2 then took 3 Mins, MiB1 about 9 mins with a transfer speed of about 35-45 Mb/sec

Just wanted to let you know that not all "Format" operations are equal.

 

NOW a question. The Skoda Portal says: "The SD card can work with just one map. To avoid unnecessary downloading, please check your map version in your navigation system."  I don't want all of the Europe maps. Does anyone know how I can select just the ones I want?

I  believe you have to do the full download. My understanding of that warning is to make sure you aren't downloading the same version you already have.

You have no choice; it's all or nothing.

Good to know........waiting on the Amazon delivery this morning and will update (or try to) this evening,

Right......it's all loaded on the SD card.

I'll attempt the update in the morning while driving to my first business call.............fingers crossed!!

I did the update to my Columbus with the 2019-20 maps on Tuesday. I was on the drive with my intelligent a battery charger connected.  It worked first time and took 38 mins. Looks like before but I did notice that when selecting a destination, it showed the Country as "UK" . Never saw this before (car was second-hand). When I started to enter W then  O (for Worcester) most characters were greyed out and once I entered R it focused on Worcester.

Not tried Post codes yet.

Thanks everyone for all the information on the site.

Yep, mine worked perfectly and as described.  I done it while in rush our traffic this morning, it took around 40mins.
