Micro SD cards

GO 5100
A new Europe UK and Ireland update is available.

Last time I did an update it used more than 200MB of my remaining internal 8GB memory (GO5100) and only left me with 160GB remaining.

I am concerned that if I do the latest update I could run into problems with enough memory and who knows what sort of mess I might be in then.

Micro SD card technology also seems to be a minefield when it comes to all different specifications and memory size. Can anyone advise me as to what type and size of a micro SD card I need to buy?

Probably covered on an existing topic, but too stupid to get a successful search.
I would suggest a 32 GB Class 10 by any brand name manufacturer.
The difference in price to a 16 GB card i small and it will allow to put additional maps on it without worrying.
Yes a Sandisk 32GB would be my preference.

Hopefully the TomTom GO 5100 accepts up to 32GB memory Micro SD Card.

The array of different micro sd card specifications still confuse me.

Would the Sandisk 32 GB SDHC Class10 White/Grey be good
would the Sandisk 32 GB SDHC Class10 U1Red/Grey be best
does it matter?
I don't think it matters as you are not taking movies.
I have been using Kingston Technologies for years and Lexar when on special.
For the map it is OK if it is a true class 10.
Bought, inserted and formatted (for maps) the Sandisk 32GB Class10 80MB/sec White/Grey micro SD card.

Updated the latest map (V10:10) and remaining internal memory still left with 53MB. New memory card not needed on this occasion.

Was keen for the new 32GB memory card being used for the map update to see if the whole map was removed from the internal memory and installed in the new card, OR if the map was split between internal memory and the new card.

No doubt that sometime in the future the new card will be needed and I will find out then what happens.
Map won't ever be split, but if it continues to grow, you'll see it move.
