Tomtomhome will not recognize my device

SOURCE: TomTom Home

I had a similar problem when trying to update my dad’s old TomTom Go300. I bought a new map and downloaded TomTom Home 2 (as instructed on the website) but found that the Go300 was recognised by the computer it wasn't recognised by TomTom's own Home 2 software.

To cut a long story short I uninstalled Home 2 and downloaded Home 1 (from http://www.tomtom.com/plus/service.php?ID=17 Home 1 is the one on the right, listed as being the version of Home you use for Navigator 6).

Then when I switched the Go300 on it was recognised by Home1 - although the new map I had bought wasn't listed as being available for download.

However, I updated the Go300 with the available listed free updates, then switched it off.

Downloaded Home 2 again and switched the Go300 on - this time it was recognised by the computer and the new map I had bought was available to download.

So far so good - the only problem was the the postcode search facility was not the same as it had been - I could now only search the first 4 digits of the postcode. There is a fix for this on the tomtom website:

http://www.tomtom.com/support/index.php?Language=1&query=postcode&FID=9852

which I followed and which worked.

Hope this may be of some use to someone! It took me hours to figure it all out. But it's up and running now.

I read and read and re-read the TomTom website looking for any info that would help but came up with nothing. A few hours later and the air thick with torrents of language I didn’t think I was capable of I discovered that I needed to download Home1 first and let the Go300 connect to the computer via Home1 before it would be recognisable by Home2. Okay…
On the website, though, Home1 is listed as being the version you use if you have TomTom Navigator 6. It’s not even called ‘Home 1′. Confusing eh? Anyway, I downloaded that and from there found that I could get my new map onto my Go300. Once the map and other updates were installed and I had switched the thing off I then found that Home2 recognised it at last.
That had to be one of the most ridiculously long-winded things I’ve had to do on a computer, mainly because TomTom’s confusing advice on their website made the whole process so damn difficult. Perhaps they hoped I’d give up and buy a new one? Tsk.

SOURCE: After update screen just says Problem with map.

Hi, I am a complete ignoramus when it comes to this sort of thing but I am pretty sure that you have the same problem I have, I updated my GPS just like you did because, heck, that is what TOMTOM recommend and hey presto I wound up with an application 'core' of version 8.x trying to access a map with a version of 7.x. Doh! You would have thought the damn install app would figure this out and NOT install wouldn't you ? Great, I barely know how to turn on a computer and I have to deal with this ****! My GPS unit is a GO 720.
Anyway the options were to fess up $100 for the new version map - or, um, well, patch it myself :-)
At this point I decided that I would patch it myself as:  a) I hold TOMTOM completely responsible for buggering up my GPS without warning and  b) I NEED my GPS right now, not whenever TOMTOM get back to me with a reply to my query about why this happened 
Here are the two links I used to patch my GPS, and yes it took a couple of hours to download and  sort it out.

Where it says...
For have a working map you must:
- Patch your 'ttsystem' file and 'Tomtom Home' with this tool:

Password: demonfatal
- Use the Keygen for patch your map
Keygen for map :

Password : demonfatal

 (Note I selected this map and it seems to work Australia_815_2086)
The new map would not work until I replaced my 'ttsystem' file with the one from the link below - dunno why.

Remember to use TOMTOM Home to back up your current GPS settings/configuration in case you balls up the patching process - frankly I don't trust TOMTOM Home to do a good enough job so maybe in addition it would be a good idea to connect the GPS to your computer and use something like Acronis to create an image... 
good luck

You'll have to remove enough stuff to make room for the new map. I had the same problem which is how I found this site. Turns out, the new map is larger than the one that came on the unit. The 1 GB of available space is pretty much all used when you get the GPS. Just copy all the voices and POIs that you aren't planning on using to your computer in case you change your mind later (you can just download them again for free too). As for the voices, only one works for text-to-speech anyway and that would be Samantha though a male voice is available for download.

You'll need to clear just under 4 MB to make room for the new map, and that's if you haven't added anything. Having the drive/memory on this unit just larger than the map makes it very difficult to get much use out of TomTom's great add-ons.

I have managed to solve the problem of loading a new map on my Go700 using a Mac. I discovered that Tomtom is incompatible with the Leopad operaying system, despite the protestations of the idiots at Tomtom ,so I reverted to an older Mac using Tiger.
Taking the instructions given to crinold, I tried to erase the disc on the 700 using home 1.5 - and it didn't work. So I went to disc utilities, highlighted and erased the Tomtom disc, and opened home 2,5. After being refused entry several times, like being told to load an already loaded device, I persevered, and managed, slowly, to add the map I had bought for 78 euros. T]One point oif interes is that when I bought the map, they site stated it would cost 63 pounds sterling, but switched it to euros when the invoice arrived. at a rate very favourable to Tomtom - funny, that.
This is sharp practice,probably illegal in many countries,, but, to be honest, dealing with the mysterious Tomtom company is so frustrating, that I don't have the time or inclination to fight them for the money they cheated from me.
How they survive with such an awful product and extremely bad after sales service is hard to understand - perhaps they won't ... we live in hope.

Sounds like you are trying to install tt home from your tt device. Go to the tt website and download from there.
