Memory card on my Start 42 — TomTom Community

Memory card on my Start 42

I have a Start 42, withe a serial number starting XT. It came pre-loaded with European maps. I want to add US maps. I have bought a 8GB Micro SDHC but when I attempt to install the US maps I have bought I get the Not enough Storage message and a request to either remove stuff or buy a memory card. How should I proceed?

    The latest NAV4 Full Europe Map size is now 8.465GB... Also the fact that the MapZones have now also exceed the 8GB of the NAV4 on-board Memory... This is an unfortunate, but real Catch22 situation....
    The Memory Card can only contain Maps or be used to transfer Planned .ITN or .GPX Routes
    The Map cannot be split across the on-board Memory and a Micro SDHC Card... For the new larger Maps maps you need to install a Branded Class 10 Micro SDHC memory card
    The latest Full Europe Map is 8.465GB so a 8GB Memory Card is useless, a 16GB or 32GB is required (32GB is the Max size Class 10 Micro SDHC Card for a Tomtom device)

    Catch22 situation No Maps Found Error....
    Tomtom are allocating a small map to install on the on-board Memory of the NAV4 devices, to give access to the Micro SDHC Card Format Option
    The advantage of the small Map would be plenty of working space on the device (400 MB is considered the minimum Free Space the more Free Space the faster the device will operate)...
    The smaller map will also act as a 'Keeper' This will enable the device to keep running on the smaller Map and avoid the Catch22 situation No Maps Found Error, where the device won't boot-up past the No Maps Found Error to allow access to the 'Format option' to allow the use of a 16GB or 32GB Micro SDHC memory card
    Also if you ever need to remove the Micro SDHC Card for any reason... Like transferring pre-planned routes via a Micro SDHC Card or Formatting a new/replacement Micro SDHC Card, the Keeper Map will allow the device to keep running

    If you wish to just stick with using the internal memory Instead of using a Micro USB Card
    Tomtom have released the Europe map in different Map Cuts (Map zones)... Will any of these new Maps suit your travel requirements ???
    More information Here...

    If Required maybe @VikramK or @lampard the Forum Moderators will allocate a smaller Map Say the UK&ROI Map to the account of your NAV4 GO 510

    Thanks for your very full reply but:

    I Is Nav4 a particular TomTom model (because as I said I have a Start 42)?

    2 My pre-loaded map is Western Europe, which according to your website is only 4177MB. I understand the principle though that you are explaining so a question: if you guys allocated a small map to me that I could load onto my machine, would I be able at no additioanl charge to put my Western Europe maps on one card and my US maps (bought but not downloaded) on another, and just swap the card over depending on where I am?

    3 As I mentioned in my original request for help, my Start 42 has a serial number beginning XT. According to your website that means the biggest card it will take is 8GB. Is that really the case (because my local Halfords and other IT stores near me) don't stock 8GB cards? And, if it is, do you stock 8GB cards?

    Thank you in advance for your help on this.

    Thanks DougLab. And you have made me realise I have been making a basic mistake and assuming I had to use a memory card of 8GB or less. smh!!
