Tomtom One V4 (1GB model) - Features/differences/improvements Options

[PRAXXUS]

N.B. Originally posted on tomtomforums.com

Ok, after playing around with the new TT1 v3 (1GB internal) I figured we need a new thread dealing specifically with TT1 v3.

Here's what I found so far;

1. The box looks almost identical to the TT1 v2, except for the absence of the SiRFStar III logo on the back of the box. Also the Technical specification states "Internal Memory: 1GB". It does say that there is 32MB RAM-266MHz CPU, but the box does not include any SD card! I posted pictures of the box including close-ups somewhere on this forum, I think the thread title was 'TT1 no longer available in Canada' (?).

2. When booting up the unit for the first time, the start-up splash screen and basic interface is the same as the TT1 v2, however, I'm suspecting that there is some differences in the main menu, as I could scroll several pages and now it only has 2. I'm not sure, as I don't have the v2 to compare. :confused:

3. Also, note that the unit comes with the latest version of US/Canada Map pre-installed (v665.1293), and latest OS (v6.56).

4. When connecting to the computer via USB, I noticed a change to the small flashing logo when the TT1 communicates with the computer. On the old TT1 v2 it was a small flashing blue book with white TomTom hand logo. Now it is a small flashing blue disc drive logo. Once connected for the first time, it asks for communication rights to TomTom HQ and then notifies of new updates (QuickGPSfix and Phonebook (??)), not sure what the Phonebook download is...any ideas. Looking at the installed items I see the usual stuff, voices, maps (USA/Canada, Guam), and Europe Satellite image, but the lack of the North American Satellite image...not sure if it's on the enclosed CD or not, I'll have to check.

5. So the question now remains, if the unit comes with 1GB internal memory and all the maps, voices, etc are installed in there, what is the SD slot for and how do you access data between the two memory areas, in other words how do you access internal memory and SD memory? After disconnecting, the unit from the PC and installing my old 2GB SD card to see what happens the system immediately boots off the SD card NOT the internal memory!! :eek: As the old modified splash screen was booted and the old US/Canada map activation code request was presented. Since the old map was used on the old TT1 v2 and activated using the old units device code, it would not allow me to boot past the map activation screen, unless I authorize the map with new codes :mad: Assumption: The TT1 upon boot-up searches the SD card slot 1st for working boot-records, if that fails it then checks internal memory for boot records. Therefore, you could make a copy of all internal memory information, copy it to the external SD card, delete all data in the internal memory, boot off the SD card and use 1GB of free internal RAM for the OS Also, inserting a blank SD card with, lets say, videos to play using Media Centre, how would you tell the TT1 to access data located in that directory? Perhaps, new version of software have to be written to give the option to look for data in other memory resources. As I write, I'm making disc images of the SD card and the internal memory before tinkering any further.

Final thought, with 1GB of internal memory and the option of booting off either internal or external memory opens up new ways to manage data and more specifically system resources (memory). Question is, does the internal memory work faster than the external SD card for data access? Time for field tests on that subject - anyone...

UPDATE 2007.04.10:
Made disk images (master) of old SD card with TT1 v2 system and new TT1 v3 internal system. I was wondering if the boot sequence is related to the volume name of the SD card. While formating the SD card, I wondered if keeping the original 'TomTom' volume name or changing it would effect boot sequence. I'll try changing the volume name to something else and see if that has any effect. I'll copy the contents of internal memory to the SD card, delete the internal memory to free up system memory resources and try running the system from the SD card al la TT1 v2.

UPDATE: 2007.04.10:
Formated SD card and installed in TT1, booted TT1 and got error message (picture of TT1 with SD card and red 'X" through it) looks like the SD card will only work with a valid system on it, no blank SD cards allowed. Therefore, TT1 boot sequence is; look for SD card boot record, if no SD card, look for boot record on internal. If SD card is installed and no boot record, display error page! So, now lets try copying the contents of the internal memory to the SD card, wipe the internal memory (freeing up 1GB for system resources) and boot off SD card. Quick note: current internal free memory is 3.8MB - booting from internal. - will post update with pics later.


UPDATE: 2007.04.11
The image below shows the TT1v3 system resources and app versions booted from the 1GB internal memory.
Note the amount of memory FREE (3.8MB). No external SD Card installed. This is stock TT1 v3.


Assumption: If deleting the contents of the 1GB internal memory and booting off external SD card. Will the TT1 v3 recognize 1GB free memory?

I backed-up in multiple area the contents of the 1GB internal memory. I formated the 1GB internal memory, and inserted the external 2GB SD card with the contents (data) from the internal memory. Booted the TT1v3 from external, and accessed the resources info page. See image below.

Notice that the FREE memory heap remains the same:eek: :confused: If the TT1v3 is using internal memory for system resources why after freeing up more than 32MB does it not access that extra memory? :confused: Is there something within the TT1v3 application itself that locks the amount of resource memory to only 32MB? If so, perhaps the tt1v3 has a slightly modified version of the OS to take into consideration the 1GB internal memory, if so, then loading the OS from TT1v2, may access ALL the 1GB internal memory. I have a backup of the old TT1v2 system, but the map wont work (activation code issue from another unit). How do I copy the map from the TT1v3 system onto the TT1v2 system and activate it for t his unit? anyone help

First thing we need is a better name to call it!
The second TT One to be released (AKA the "New Edition") was actually called the "v3" (there was no "v2" ever released).

THIS model with the 1GB internal memory refers to itself as the "v4".

With your permission, could we edit the title of this post to reflect that, please?

Technically you are correct , although this is physically the third (3rd) version or, in keeping with iPOD tradition, 3rd Generation of the TomTom ONE. Perhaps it should be referred to as TT1 Gen3 or TT1 g3.

I'll leave it up to you to decide, or perhaps a poll to the forum members as to how to refer to the 3rd version/generation of the TT1.

[Andy_P]

Trouble is, TT themselves have always referred to the old "New Edition" as the v3, so you can see the confusion... typical TomTom!

Anyone else got any thoughts?

I'm hoping you understand that the 1GB of hard drive memory is different from the 32MB of RAM.

HDD memory is where you store stuff and RAM is memory that is used to retrieve stuff. I keep hearing you mentioning about using the 1GB memory by deleting the app and using an SD card instead. I hope you mean something else and you're not thinking that the 1GB is RAM.


Anyway.. at least you get 32MB. We only get 29MB of RAM in the old new edition TT1. That might explain why you always get 3.2MB free and we get 0.2MB free.

I say if TomTom is going to call this TomTom One v4, we should do the same...
(and the screen shots seem to suggest that)

Nextrouter... I don't think the this new TomTom One has an HDD. I think it has internal flash memory.
(like the Ipod Nanos)

But that being said. The TomTom has Internal flash memory AND standard ram. And it seems to have 29MiB (or 32 MB damn stupid addvertising BS (see http://en.wikipedia.org/wiki/Mebibyte for differences between MB and MiB))

sorry, It seems to have 29MiB of ram. Clearing the Flashram will not affect this, nor will it affect the free ram.

So I don't seen an advantage to moving the maps from the Internal Flash Ram to external SD cards.
Well the Internal flash ram is likely *a little* faster than the SD card, so whatever that is worth to you...

right, flash. I stand corrected. Thanks.
