Hello.
Please I need little help with TOMTOM One 1GB version
- all I need is maps for Central Europe (Slovakia, Czechia, Austria, Hungary, maximum also Croatia, Slovenia) ... because I know I am limited possibility due to internal capacity


Actual parametres: (Latest Update: 27.12.2013 :thumbdown: )

Central_and_Eastern_Europe_915_5106
Bootloaderversion=5.5136

It is possible to update without open box and resolder the memory card ?
Thank for all information.

Look at Poteo_Roke's document to decide what map you need:

Thand You.
I already see that excel - great work.
But what I found it will be not possible in fully coverage of maps - so I choose small one (Central Europe East = 365,60 Mb due to lack of internal space capacity).
Now I must found how all another update - but already I am not sure what all I neet do update NavCore and something else ?. :017:

This is the way to do it all good ? -> tutorials/how-update-patch-tomtom-nav3-devices-t21959.html

No, the information on that link you posted is of no use for you.

The map you refer to is Central Europe East 1170.13171 = 365.60MB

It might be suitable for your TomTom One device but it depends on what navcore is already installed on it...what is it?
