This FAQ only applies to GO x20, x30, x40 and x50 devices connecting to TomTom HOME [support FAQ - Updating software].
 
This FAQ address a rather simple issue which, however, can cause various sorts of problems and strange behaviour. The basic issue is that you might sometimes end up installing some software on both the internal memory of your device as well as the memory card.
 

Symptoms


The issues I've seen caused by this include (but are not limited to)
  • Freezing on startup
  • Rebooting (see also this FAQ [Rebooting device])
  • TMC not working
  • Various problems with the map
  • Poor/no GPS connection
  • Issues with Bluetooth connection with a phone.
  • Issues with computer voices (the ones that read street names)
In short, if you're experiencing any unusual behaviour with the above mentioned device models, this is the first place to check.
 

Troubleshooting


The problem is rather easy to detect and solve.
-       First, remove the memory card from your device and test if there's any change in the behaviour
-       To confirm, connect your device to your computer and access the memory card (shown as a removable drive in the File Explorer, or on your Desktop in Mac)

The internal memory is usually called either Internal or TomTom followed by a drive letter on PC and TomTom Disk on Mac.

If in doubt of which one is the internal memory and which the memory card, compare the sizes of the drives or remove the memory card from the device and see which drive disappears.
  • You should have only map folder(s)* on the memory card, e.g. Western_and_Central_Europe_2GB, North_America, etc. (If you have installed music files, they should be in a folder called MP3)
  • If theres anything else on the memory card, remove it
  • (Re)start TomTom HOME and install any updates it offers. IMPORTANT: Always choose Internal memory (see comments below for more info)
  • If TomTom Application is offered, repeat the update process until it is no longer offered
*Also zip codes (zip folder) should go where the map is.
 
I hope this helps.
 
Cheers, Mikko

I do not agree with that statement... 😃 ...at least with an older TTH (maybe 2.8.xyz) selecting Internal forced me to not download my full Europe but zone map since the full Europe is over 2,1Gb.

I may have even opened a ticket with support about that!

Now I always select External when running TTH and I do not have any problems!! 😃

Hi Giangi,

Thank you for your feedback!

My advice was primarily for avoiding getting the app installed on the memory card. In fact, I'm not quite sure how people end up getting the app on the memory card since TomTom HOME since 2.6 or so should be smart enough to install items where they belong, i.e. maps and music to memory card and rest to internal memory. So it shouldn't actually make any difference which one is selected. But selecting internal memory works regardless of TomTom HOME version so I'll stick to that for the time being.

By default TomTom HOME updates the map zone in the internal memory if present, even when a memory card is present. In such a case http://uk.support.tomtom.com/app/answers/detail/a_id/15227" target="_blank is needed. Of course changing map zone gives an option for the full map, if a memory card is present, but this would leave the map zone in the internal memory.

Getting offered only map zones when a memory card is present would first indicate an issue with the memory card, i.e. http://uk.support.tomtom.com/app/answers/detail/a_id/2634" target="_blank.

But I'm going to do some testing when I have time and get back here when I have some more solidly grounded information on this matter.

Cheers, Mikko

Bingo, that was the problem... I have re-read my old  issue 111119-002148 (November 2011) and it's a shame that TTH is still not able to manage such a situation!

When space is available on external memory TTH should be smart enough to ask the users what to do, something like:

To update your current map stored on internal memory you have two options:

  1.  since there is not enough space available on internal memory you can install a map-zone
  2.  since you have space available on external memory you can remove map from internal memory and install the new one on the external one (suggested option)
For option 2 of course TTH should not just delete the map from internal memory but must carry over to the new destination user's settings and pois!

For me that is so easy and logical that I really cannot understand why is still not done! 😠

BTW: my solution was to manually movethe map from internal memory to the SD and then TTH updated that one with my full Europe and not a map-zone... (at that time I was running TTH v2.8.2.2264)

Hi Giangi,

I'm glad if I was able to shed some light to this matter. There's definitely some space for improvement in TomTom HOME here.

As mentioned, I'll do some testing of my own as well and post my findings here. I'll then forward this thread on so that these things could be improved in TomTom HOME.

As for troubleshooting, I tend to go for the easiest/quickest solution. In your case that would be deleting the old map as the new one has to be downloaded anyway.

Also I would always recommend using the latest TomTom HOME version (currently 2.9.4.3058) as these things change per version and at least I don't keep track on the behaviour of old versions.

Thanks again for your feedback!

Cheers, Mikko

That was another big problem of older TTH: all the user's stuff were always deleted! Furtunately with v2.9.xxx things are going better...

BTW: I'm running the current version... I wrote that at that time (2011!) I was using...

Ive had these elements on my card for a few years now - never excperienced any problems - Am i forced to do any adjustments to the content as a result of the latest Home-version, awaiting the 9.05 W&C.Europe map?

@ Giangi: Thanks for the clarification

@ Rubach: I would say: If it's not broken don't fix it ;)

I.e. if you're not experiencing any strange behaviour, just leave it like it is. But if you do at any point run into problem - and as mentioned in the original post, they can be of various nature - you know where to start troubleshooting.

If you do need to clean up your memory card, make sure to back up any personal content.

Running full back-ups weekly and update the unit at least one a week - no problems there.

Thx for the reply :D
My unit (GO530) regularly crashes and restarts and so on - but I have no choice to use a memory card for everything - the internal memory died a few weeks after the warranty ran out 😞 Any ideas how to get round the problem?

As you can't really replace the internal storage just like that, you can use the memory card only.
Hi, thank you but I don't really understand your reply - I can't use the memory card like that but I can?

The internal storage and the memory card are two different things.
I have a tomtom go 300. when I try to update the map with tom tom home, it says i have to update the system at first.

I just try but, after made the back up, the program stops during the sistem updating and the program stops.

After that the device does not work at all.Th SD ia no more readeble and, to restart the system I have to past and copy the files from back up to the SD, directly on my PC.

At this point the TTGO300 restart but without the voice!!!!!!! So, the conclusion is that I cannot update the maps and I lost the voice.!!! 
I am having a problem updating my old GO 300.  I just need to update to a more current map.  I can get my computer to recognize the device but even the newest version of My TomTom doesn't recognize that the unit is connected.  is there a way to just download the latest maps for the USA to my computer and manually load them onto the SD card?  I don't mind paying for the new map I just don't want to do that if I can't get it on my legacy device.  Can someone let me know if I can just download the file and replace the one on my card??  Thanks in advance.  Steve Bushamn

You need TomTom HOME, not MyTomTom.
Hallo, I have a problem whit my tom tom go 930 T

Provide more detail......

What application is on your device? What map and version?

And, most importantly, what problems?
Well, just connecting my Tom Tom GO 40 for the first time, after multiple failures looks the software is finally working. Only 3 hours wasted of my time.

The internal memory has 273 mb free, the original maps weight 5700 mb approx, and the next update weights 6100 approx.

So I bought the machine yesterday, the maps are from august last year, and in order to make the first update I have to buy a memory card.

The question is actually, how on earth can you put the maps without using a memory card that Tom Tom is not kindly including in the product they sell!!!!
